Standard Practice for Linear-Elastic Plane-Strain Fracture Toughness Testing of Aluminum Alloys

SIGNIFICANCE AND USE
5.1 This practice for plane-strain fracture toughness testing of aluminum alloys may be used as a supplement to Test Method E399. The application of this practice is primarily intended for quality assurance and material release in cases where valid plane-strain fracture toughness data cannot be obtained per Test Method E399.  
5.2 It must be understood that the interpretations and guidelines in this practice do not alter the validity requirements of Test Method E399 or promote the designation of data that are invalid according to Test Method E399 to a “valid” condition. This practice is primarily concerned with cases where it is not possible or practical to obtain valid data, but where material release judgments must be made against specified fracture toughness values. Where it is possible to obtain a valid plane-strain fracture toughness value by replacement testing according to Test Method E399, that is the preferred approach.
SCOPE
1.1 This practice is applicable to the fracture toughness testing of all aluminum alloys, tempers, and products, especially in cases where the tests are being made to establish whether or not individual lots meet the requirements of specifications and should be released to customers.  
1.2 Test Method E399 is the basic test method to be used for plane-strain fracture toughness testing of aluminum alloys. The purpose of this practice is to provide supplementary information for plane-strain fracture toughness of aluminum alloys in three main areas:  
1.2.1 Specimen sampling,  
1.2.2 Specimen size selection, and  
1.2.3 Interpretation of invalid test results.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3.1 Exception—Certain inch-pound values given in parentheses are provided for information only.  
1.4 This standard is currently written to accommodate only C(T) specimens.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Practice for Aluminum Alloy Extrusions Press Cooled from an Elevated Temperature Shaping Process for Production of T1, T2, T5 and T10-Type Tempers

ABSTRACT
This practice establishes the controls necessary for production of extrusions cooled from an elevated temperature shaping (extrusion) process for the production of T1, T2, T5 and T10–type tempers. The equipment shall be used for billet preheating, extruding and quenching. Quenching methods may consist of, but are not limited to, air, water or water/glycol mixture in forced air, water spray, fog or mist, standing wave, a quench tank or another pressurized water device, or a combination thereof. Surveillance tests should include tensile properties for all material and metallographic examination to confirm that the elevated temperature shaping process has not resulted in eutectic melting or subsurface porosity from hydrogen diffusion. Specimens shall be sectioned in the plane perpendicular to the direction of the extrusion, polished to an appropriate fineness, mildly etched with an etchant such as Keller’s reagent to reveal any evidence of eutectic melting. Specimens shall also be subjected to tension and hardness tests. During the extrusion process, the following temperature measuring points should be monitored and controlled as per the producer’s internal procedures. The measuring points include but are not limited to: billet or log temperature in the heating equipment, billet or log temperature after heating and before charging into the extrusion press, temperature of the extrudate at the press exit, temperature of the extrudate at quench entry, temperature of the extrudate at the completion of quench, and billet temperature shall not exceed the maximum temperature for the alloy. Artificial aging shall be accomplished using times and temperatures as necessary to achieve required properties.
SCOPE
1.1 This practice establishes the controls necessary for production of extrusions cooled from an elevated temperature shaping (extrusion) process for the production of T1, T2, T5 and T10-type tempers (see ANSI H35.1/H35.1M).  
1.2 This practice is for production of extruded product supplied in the 6xxx and 7xxx alloys shown in Table 1 in the T1, T2, T5 or T10-type tempers (see ANSI H35.1/H35.1M). It contains pertinent information to be used in establishing production practices and is descriptive rather than prescriptive. For the attainment of T3, T4, T6, T7, T8 and T9-type tempers by extrusion press solution heat treatment, refer to Practice B807/B807M.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM B807/B807M-20(Practice)
Standard Practice for Extrusion Press Solution Heat Treatment for Aluminum Alloys

ABSTRACT
This practice covers the controls required and standards for extrusion press solution heat treatment for 6xxx and 7xxx series aluminum alloys. For alloys such as 6005, 6005A and 6105 alloys, this practice is an alternative to solution heat treatment in a furnace. This practice only applies to extrusion press solution heat treatment for aluminum alloys and does not cover precipitation hardening (aging) processing. The alloy billets shall be preheated prior to being extruded. Heating methods shall include, but not limited to, induction, flame impingement, or forced air. Pertinent control points shall include billet or log temperature in the heating equipment, billet temperature upon being charged into the press container, container temperature, ram speed, profile configuration, extrudate temperature upon exiting the press platen, extrudate temperature at quench entry, quench media temperature, and quench rate.
SCOPE
1.1 This practice establishes the controls required for extrusion press solution heat treatment of the 6xxx and 7xxx series aluminum alloys in Table 1 when ASTM material specifications allow use of this process in lieu of furnace solution heat treatment. For the alloys listed in Table 1, this practice is an alternate process to solution heat treatment in a furnace, such as specified in Practice B918/B918M for the attainment of T3, T4, T6, T7, T8, and T9-type tempers (see ANSI H35.1/H35.1M).  
1.2 This practice applies only to extrusion press solution heat treatment for aluminum alloys. Precipitation hardening (aging) and annealing processing and equipment calibration shall meet the practice and requirements of Practice B918/B918M.  
1.3 The values stated in either Metric SI units or US Customary units are to be regarded separately as standard. The Metric SI units are shown in brackets or in separate tables. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM B646-19(Practice)
Standard Practice for Fracture Toughness Testing of Aluminum Alloys

SIGNIFICANCE AND USE
5.1 This practice is provided to develop and maintain uniformity in practices for the evaluation of the toughness of aluminum alloys, particularly with regard to supplier qualification, quality assurance, and material release to specifications.  
5.2 It is emphasized that the use of these procedures will not alter the validity of data determined with specific test methods, but provides guidance in the interpretation of test results (valid or invalid) and guidance in the selection of a reasonable test procedure in those instances where no standard exists today.
SCOPE
1.1 Fracture toughness is a key property for a number of aluminum alloys utilized in aerospace and process industries. Fracture toughness testing is often required for supplier qualification, quality control, and material release purposes. The purpose of this practice is to provide uniform test procedures for the industry, pointing out which current standards are utilized in specific cases, and providing guidelines where no standards exist. This practice provides guidance for testing (a) sheet and other products having a specified thickness less than 6.35 mm (0.250 in.), (b) intermediate thicknesses of plate, forgings, and extrusions that are too thin for valid plane-strain fracture toughness testing but too thick for treatment as sheet, such as products having a specified thickness greater than or equal to 6.35 mm (0.250 in.) but less than 25 to 50 mm (1 to 2 in.), depending on toughness level, and (c) relatively thick products where Test Method E399 is applicable.  
1.2 The values stated in SI units are to be regarded as the standard. The values in inch-pound units given in parenthesis are provided for information purposes only.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Guide for Hot Isostatic Pressing (HIP) of Aluminum Alloy Castings

SIGNIFICANCE AND USE
4.1 HIP of castings should be performed in the as cast condition. Post HIP inspection of castings should result in a reduction of porosity that is evident in x-ray grade and properties.  
4.2 HIP will not eliminate inclusions or surface-connected porosity in a casting.
SCOPE
1.1 This guide presents requirements for hot isostatic pressing (HIP) of aluminum alloy castings. HIPing is a process in which components are subjected to the simultaneous application of heat and high pressure in an inert gas medium. The process is to be used for the reduction of internal (non-surface connected) porosity. The document is to describe the general parameters of the HIP process, describe certification procedures and a description that the process has been followed. It is not intended to be a description of a heat treating procedure. This is not meant to supersede an end user’s specification where one exists.2  
1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
