4. Materials and Manufacture
4.1 Castings conforming to this specification shall be produced by vacuum investment casting.
4.2 Castings covered by this specification shall be in the annealed and hot isostatically pressed condition.
NOTE 1—While hot isostatic processing (HIP) may enhance mechanical properties of Ti6A1-4V castings, it has also been shown to reduce the scatter
in mechanical properties and therefore increases the confidence in reliability of castings.
4.3 Surface defects may be repaired by welding.
4.3.1 Weld repair shall be carefully executed as per written procedures by individuals qualified to perform those procedures.
4.3.2 ELI weld rod conforming to Specification F 136 shall be used where filler metal is needed.
4.3.3 Weld repairs shall be performed prior to final thermal processing.
NOTE 2—Under certain circumstances, a weld repair will act as a stress riser. Therefore, care should be exercised in the location and extent of weld
repair as it relates to regions of the implant where significant stresses might be incurred.
4.4 All alpha case shall be removed by suitable means such as chemical milling or machining prior to HIP processing.
4.5 Parts shall be furnished in the descaled and cleaned condition in accordance with Guide B 600.
4.6 Other thermal processes that meet the specific needs of the purchaser may be mutually agreed upon by the supplier and
purchaser.
5. Chemical Composition
5.1 Product castings shall conform to the requirements prescribed in Table 1. The supplier shall not ship material outside the
limits of Table 1. Chemical analysis shall be performed on a representative specimen cast from each heat using the same general
procedures used in casting implants.
5.1.1 Requirements for the major and minor elemental constituents are listed in Table 1. Also listed are important residual
elements. Analysis for elements not listed in Table 1 is not required to verify compliance with this specification.
5.2 Product Analysis—Product analysis tolerances do not broaden the specified heat analysis requirements but cover variations
betweenlaboratoriesinthemeasurementofchemicalcontent.Thesuppliershallnotshipmaterialthatisoutsidethelimitsspecified
in Table 1. The product analysis tolerances shall conform to the product tolerances in Table 2.
5.2.1 The product analysis is either for the purpose of verifying the composition of a heat or manufacturing lot or to determine
variations in the composition within the heat.
5.2.2 Acceptance or rejection of a heat or manufacturing lot of material may be made by the purchaser on the basis of this
product analysis.
5.3 For referee purposes, use Test Methods E 120, E 1409, and E 1447 or other analytical methods agreed upon between the
purchaser and the supplier.
5.4 Ensure that the samples for chemical analysis are representative of the material being tested. The utmost care must be used
in sampling titanium for chemical analysis because of its affinity for elements such as oxygen, nitrogen, and hydrogen. In cutting
samples for analysis, therefore, the operation should be carried out insofar as possible in a dust-free atmosphere. Cutting tools
should be clean and sharp. Samples for analysis should be stored in suitable containers.
6. Mechanical Requirements
