BS ISO 5832-11:2014 pdf download.Implants for surgery一Metallic materials Part 11: Wrought titanium 6-aluminium 7- niobium alloy.
This part of Iso 5832 specifies the characteristics of, and corresponding test methods for, the wrought titanium alloy known as titanium 6-aluminium 7-niobium alloy (Ti-6-Al 7-Nb) for use in the manufacture of surgical implants.
NOTE The mechanical properties of a sample obtained from a finished product made of this alloy might not necessarily comply with those specified in this part of ISO 5832.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

3 Chemical composition
The heat analysis shall conform to the requirements as to the chemical composition prescribed in Tablel. Ingot analysis can be used for reporting all chemical requirements except hydrogen, which shall be determined after the heat treatment and pickling procedure.
4 Microstructure
The microstructure, when examined as indicated in Table 3, shall be alpha + beta, and shall correspond to ISO 20160:2006, micrograph A 1 to micrograph A 9, for annealed material.
5 Mechanical properties
The tensile properties of the alloy, determined as specified in Clause 6, shall be in accordance with the requirements of Table 2.
Should any of the pieces not meet the specified requirements or should they break outside the gauge limits, two further test pieces representative of the same batch shall be tested in the same manner. The alloy shall be deemed to comply only if both additional test pieces meet the specified requirements.
If any of the retests fail to meet the appropriate requirements, the product represented shall be deemed not to comply with this part of ISO 5832.
6 Test methods
The test methods to be used in determining compliance with the requirements of this part of ISO 5832 shall be those given in Table 3.
Representative test pieces for the determination of mechanical properties shall be prepared in accordance with the provisions of ISO 6892-1.BS ISO 5832-11 pdf download.
