Microstructure and wear resistance of Ti-3Zr-2Sn-3Mo-15Nb (TLM) alloy
The effects of heat treatment on the microstructure and phase constitution of Ti-3Zr-2Sn-3Mo-15Nb (TLM) alloy were investigated by optical microscopy,X-ray diffractometry and transmission electron microscopy.The wear resistance of TLM alloy was tested by sliding wear in comparison with as-annealed Ti-6Al-4V and as-aged Ti-13Nb-13Zr.The results show that the specimen cooled from α+β dual phase region is mainly composed of β,α and α″ phases,while the specimen cooled from β single phase region is mainly composed of β and α phases,in which β phase is predominate.The coefficient of friction of TLM alloy treated at 680 ℃,1 h,AC+510 ℃,6 h,AC is smaller than that of others,thereby TLM alloy has a better wear resistance which is also proved by the surface topography after wear test.
