Precipitation Heat-Treatment12.1 Solution-heat-treated or solution-heat-treated and cold-work

32、ed material is normally precipitation hardened by thepurchaser after forming or machining. For the purpose ofdetermining conformance to specified mechanical properties ofTable 3, a sample of the as-supplied material shall be heattreated as shown in Table 8. Other heat treating temperaturesand times

33、may be preferred for end products of this material.12.2 The solution-heat-treated and cold-worked test speci-mens shall be heat treated at a uniform temperature of 600 to675F (316 to 357C) for the time shown in Table 8.12.3 Special combinations of properties such as increasedductility, electrical co

34、nductivity, dimensional accuracy, endur-ance life, and resistance to elastic drift and hysteresis in springsmay be obtained by special precipitation-hardening heat treat-ments. The mechanical requirements of Table 3 do not apply tosuch special heat treatments.12.4 Mill-hardened products have been pr

35、ecipitation heat-treated by the manufacturer. Further thermal treatment is notnormally required.13. Sampling13.1 Sampling shall be in accordance with SpecificationB 248, Section 7, except that the heat size is defined as 12 000lbs (5455 kg) or fraction thereof.14. Specimen Preparation14.1 The tensio

(9.52 6 1.59 mm) in width and a

37、nyconvenient length. Specimens shall be precipitation heat-treated after cutting and prior to testing. Precipitation heat-treatment parameters for these bend tests shall be in accordancewith 12.2.15. Test Methods15.1 The method for determining chemical analysis forcompliance and preparation of certi

38、fications and test reportsshall be at the discretion of the reporting laboratory.15.2 In case of dispute, the test methods found in Annex A1shall be used for determining chemical requirements for theelements and ranges shown in Table 1.15.2.1 When analysis for unnamed or residual elements isrequired

39、 in the purchase order, the method of analysis shall bemutually agreed upon between manufacturer or supplier andpurchaser.15.3 Bend-test specimens, shall be tested by clamping themfirmly between a flat jaw and the test radius, as shown in Fig.1. The test specimen shall be bent approximately 90 aroun

40、dthe test radius, using a tangential wiping motion with adequateradial pressure to ensure continuous contact between thespecimen and the test radius. Test specimens shall be bent tothe full 90 bend position. The test radius shall be within 66 % of the nominal radius up to 0.010 in. (0.254 mm),exclus
