26、pon by the purchaser and producer.5.2 The melting method used to produce the ingot shall be reported to the purchaser on the certification.2 For referencedASTM standards, visit theASTM website, www.astm.org, or contactASTM Customer Service at serviceastm.org. For Annual Book of ASTM Standardsvolume

27、information, refer to the standards Document Summary page on the ASTM website.B977 1325.3 The melting method shall be at the discretion of the producer, unless specified in the purchase order.6. Chemical Composition6.1 The chemistry of titanium and titanium alloy ingot covered by this specification

28、shall conform to the requirements for thespecified grade as prescribed in Table 1.6.1.1 The elements listed for each grade in Table 1 are intentional alloy additions or elements that are inherent to themanufacture of titanium sponge or ingot.6.1.2 Elements intentionally added to the melt, including

29、additions made via revert additions, must be identified, analyzed andreported in the chemical analysis. Elements not listed in Table 1 for the specified grade shall not be required.6.1.3 When agreed upon by the producer and purchaser and requested by the purchaser in the written purchase order, chem

30、icalanalysis shall be completed for specific elements not listed in this specification.6.2 The chemical analysis shall normally be conducted using theASTM standard test methods referenced in 2.1. Other industrystandard methods may be used where the ASTM test methods in 2.1 do not adequately cover th

31、e elements in the material or byother methods acceptable to the purchaser. Alternate techniques are discussed in Guide E2626.6.3 Product Check AnalysisProduct check analysis is an analysis made by or for the purchaser for the purpose of verifyingthe composition of the ingot. The check analysis toler

32、ances reflect the variation between laboratories in the measurement ofchemical composition. The permissible variation in the product check analysis from the specified range is as prescribed in Table2.7. Condition7.1 Surface FinishThe surface finish shall be at the discretion of the producer, unless

33、specified in the purchase order.7.2 When specified, the ingots shall be conditioned on the surface to standards agreed upon between the manufacturer and thepurchaser.7.3 Titanium and titanium alloy ingots shall be free of imperfections that would be deemed injurious by the standards ofacceptability

34、agreed upon between the purchaser and the manufacturer.7.3.1 The manufacturer shall be permitted to remove minor surface imperfections. Surface imperfections may be removed upto 1 in. (25 mm) deep from the ingot surface. Areas adjacent to the imperfection shall be blended smoothly into the ingot sur

35、faceat a slope not less than 3:1.8. Retest8.1 If any sample or specimen exhibits obvious contamination, improper preparation, or flaws disqualifying it as a representativesample, it shall be discarded and a new sample or specimen substituted.8.2 If the results of any test are not in conformance with

36、 the requirements of this specification, the original sample from the ingotmay be retested or the ingot may be re-sampled and tested.8.2.1 If the original ingot sample is retested, the frequency of the retest will be at least double the initial number of tests. Theretests will be compared to the ori

37、ginal value to determine if the original value is an outlier in accordance with Practice E178. Ifit is an outlier the retest values will be averaged and the averaged retest values reported. If it is not an outlier all the values willbe averaged and the averages of all of the tests become the test va

38、lue reported. If the averaged value reported conforms to thespecification, then they become the test values for certification.8.2.2 The manufacturer may resample the ingot at the non-conforming location(s) in a different area at the same axial location.The frequency of the resample will be at least

39、double the initial number of tests. If the results of the resample conform to thespecification, then the resample values become the test values for certification.8.3 The manufacturer may scalp or crop the ingot to remove nonconforming material then sample the remaining ingotposition(s). The ingot sh

40、all be acceptable if all results of the tests on the ingot conform to this specification.9. Sampling9.1 Samples for chemical analyses shall be representative of the material being tested.The utmost care must be used in samplingtitanium for chemical analysis because of its great affinity for elements

41、 such as oxygen, nitrogen, and hydrogen. Therefore incutting samples for analysis, the operation should be carried out insofar as possible in a dust-free atmosphere. Chips should becollected from clean metal and tools should be clean and sharp. Samples for analysis should be stored in suitable conta

42、iners.9.2 The ingot shall be sampled at a minimum of two locations; top and bottom. The top sample shall be within 12 in. (300 mm)of the top face. The bottom sample shall be within 12 in. (300 mm) of the bottom face.10. Significance of Numerical Limits10.1 For purposes of determining compliance with

43、 the specified limits for requirements of the properties listed in Table 1 andTable 2, an observed value or a calculated value shall be rounded as indicated in accordance with the rounding method of PracticeE29.B977 133TABLE 1 Chemical RequirementsChemical Composition (Weight %)A,B,C,DGrade CmaxOran
