Areferee analysis may be used if agreed upon by the supplier andpurchaser.7.2.4 For referee purposes, use Test Methods E539, E

31、1409,E1447, E1941, and E2371 or other analytical methods agreedupon between the purchaser and the supplier.7.3 Samples for chemical analysis shall be representative ofthe material being tested. The utmost care must be used insampling titanium for chemical analysis because of its affinityfor elements

32、 such as oxygen, nitrogen, and hydrogen. Incutting samples for analysis, therefore, the operation should becarried out insofar as possible in a dust-free atmosphere.Cutting tools should be clean and sharp. Samples for analysisshould be stored in suitable containers.8. Mechanical Requirements8.1 The

33、material supplied under this specification shallconform to the mechanical property requirements in Table 1.8.2 Specimens for tension tests shall be machined and testedin accordance with Test Methods E8/E8M. Tensile propertiesshall be determined using a strain rate of 0.003 to 0.007mm/mm/min (in./in.

34、/min) through yield and then the crossheadspeed may be increased so as to produce fracture in approxi-mately one additional minute.8.2.1 Bar, Forging Bar, Shapes, and WireTest accordingto Test Methods E8/E8M. Should any test specimen not meetthe specified requirements, test two additional test piece

35、srepresentative of the same lot, in the same manner, for eachfailed test specimen. The lot will be considered in complianceonly if all additional test pieces meet the specified require-ments.8.2.2 Tensile tests results for which any specimen fracturesoutside the gage length shall be considered accep

36、table, if boththe elongation and reduction of area meet the minimumrequirements specified. Refer to subsections 7.11.4 and 7.12.5of Test Methods E8/E8M. If either the elongation or reductionof area is less than the minimum requirement, discard the testand retest. Retest one specimen for each specime

37、n that did notmeet the minimum requirements.8.3 For sheet and strip, the bend test specimen shall with-stand being bent cold through an angle of 105 without fracturein the outside surface of the bent portion. The bend shall bemade around a mandrel which has a diameter equal to thatshown in Table 2.T

38、est conditions shall conform toTest MethodE290.8.3.1 Sheet, Strip, and PlateTest according to Test Meth-ods E8/E8M. Perform at least one tensile test from each lot inboth the longitudinal and transverse directions. Tests in thetransverse direction need be made only on product from whicha specimen no

39、t less than 200 mm (8 in.) in length for sheet and65 mm (2.50 in.) in length for plate can be taken. Should anyof these test specimens not meet the specified requirements,test two additional test pieces representative of the same lot, inthe same manner, for each failed test specimen. The lot will be

40、considered in compliance only if all additional test pieces meetthe specified requirements.9. Special Requirements9.1 The microstructure shall be a result of processing withinthe alpha-plus beta field. Microstructure shall essentially con-sist of an equiaxed and/or elongated primary alpha in atransf

41、ormed beta matrix with no continuous alpha network atprior beta grain boundaries.9.2 Determine the beta transus temperature for each heat bya suitable method and report on the material certification ifrequired by the purchaser.9.3 Alpha case is not permitted for products supplied with amachined, gro

42、und, or chemically milled or pickled surfacefinish. For other products, there shall be no continuous layer ofalpha case 0.0025 mm ( 0.001 in.) when examined at 100magnification.10. Ultrasonic Inspection10.1 All centerless ground or peeled and polished round bar 9.5 mm (0.375 in.) in nominal diameter

43、 shall be ultrasoni-cally inspected at final diameter according toAMS 2631, ClassA1. Equivalent test methods may be substituted when agreedupon by purchaser and supplier.NOTE 1AMS 2631 contains varying flat bottom hole (FBH) require-ments based on melting grades per AMS 2380. Since the FBH require-m

44、ents for Class 1 is the same, regardless of the melting grade, it is notnecessary to specify the melting grade.11. Significance of Numerical Limits11.1 The following applies to all specified numerical limitsin this specification. To determine conformance to these limits,an observed or calculated val

45、ue shall be rounded to the nearestunit in the last right hand digit used in expressing thespecification limit, in accordance with the rounding method ofPractice E29.12.
