Foreword

All technical contents of this standard is mandatory.

Using the equivalent standards ISO 5832-11:1994 "metallic surgical implant materials - Part 11. Ti-6Al-7Nb alloy was added Workers material. " For ease of use, the standard of the original international standard made the following editorial changes.

a) delete the foreword international standards;

b) delete the introduction of international standards. Appendix A of this standard is normative.

3 Chemical composition

Melting analysis should meet the requirements of detecting chemical composition, the chemical composition of the product should meet the requirements of Table 1. In addition to hydrogen in the heat treatment Pickling and outer test, other elements may be employed ingot analysis.

4 Microstructure

When tested according to the method of Table 3, the transverse annealed microstructure alpha + beta should be processed tissue, assessed in Appendix A, the type of tissue which should meet Graph A. 1 to A. 9.

5 Mechanical Properties

When tested by the method in Chapter 6, the mechanical properties shall comply with the provisions of Table 2.

If the test results of a sample from the defective or broken in an outer standard, should be the same batch of products Another two samples retest. complex Test samples were satisfactory, the penalty whole batch of qualified products. Ruofu still failed test sample case, this batch of product failure. base on needs, Production of heat-treated before reuse or resampling.

6 Test methods

Test methods should be consistent with the provisions in Table 3. Sample processing shall comply with GB/T 228 a.
