摘要

Howmedica developed the Titanium-12Molybdenum-6Zirconium-2Iron beta titanium alloy (also known as TMZF® beta titanium alloy) in the late 1980s. Two patents were issued for this high strength, low modulus, ductile, biocompatible, titanium base alloy. The mechanical properties for wrought machining and forging bar in ASTM F 1813 show higher tensile and yield strengths than Ti-6Al-4V ELI (ASTM F 136), the most widely used titanium grade for medical and surgical implant applications. According to the ASTM standard, the TMZF alloy also has improved ductility over Ti-6Al-4V ELI, which is to be expected when comparing beta and alpha+beta titanium alloys. TMZF alloy offers higher tensile strength and greater flexibility than Ti-6Al-4V alloy. Data are presented for semi-finished TMZF mill product forms in the solution-annealed condition. The influence of oxygen as an interstitial strengthening element is shown for Ti-12Mo-6Zr-2Fe and compared with common titanium alloys used in or being considered for use in the medical device industry.
