E04.02 - Terminology

SIGNIFICANCE AND USE
3.1 Standards of Committee E04 consist of test methods, practices, and guides developed to ensure proper and uniform testing in the field of metallography. In order for one to properly use and interpret these standards, the terminology used in these standards must be understood.  
3.2 The terms used in the field of metallography have precise definitions. The terminology and its proper usage must be completely understood in order to adequately communicate in this field. In this respect, this standard is also a general source of terminology relating to the field of metallography facilitating the transfer of information within the field.

SCOPE
1.1 This standard covers the definition of terms, acronyms, and symbols used in ASTM documents related to the field of metallography and metallographic testing. Terms that are only relevant to a particular standard or that are adequately defined in a general dictionary are not defined in this terminology standard.
1.2 This standard includes terminology used in metallographic areas, such as, but not limited to: light microscopy, microindentation hardness testing, specimen preparation, x-ray and electron metallography, quantitative metallography, photomicrography, and determination of grain size and inclusion content.
1.3 This standard may be of use to individuals utilizing standards of Committee E-4 as well as by those in need of a general reference source for terminology in the field of metallography.

WITHDRAWN RATIONALE
Formerly under the jurisdiction of Committee E04 on Metallography, this terminology was withdrawn in January 2019 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

SCOPE
1.1 This practice covers the drawing of binary phase diagrams and isotherms through ternary phase diagrams for publication.

SCOPE
1.1 This practice covers the assignment of designations for all alloy phases, based on the composition and crystal structure of each.  
1.2 The practice makes possible the selection of a unique designation for each phase, except that in some cases an arbitrary lower case letter is used as described in 3.4 and 3.5.  
1.3 The same designation shall be used for a given phase regardless of the system in which it appears (single component, binary, ternary, or polynary).
1.4 A procedure for selecting a temporary designation is also provided to cover those cases in which not enough information is available to assign the permanent designation.
