Název v původním jazyce

Microstructure of Ti - Mo - Zr - Ta - Sn alloy prepared by plasma melting

Popis výsledku v původním jazyce

The β titanium alloys are promising candidates for biocompatible implant applications because of their low Young modulus when compared to (α + β) titanium alloys. In this study three β titanium alloys Ti-12Mo-6Zr, Ti-8Mo-6Zr-2Ta-2Sn and Ti-8Mo-6Zr-2Ta-4Sn (in at%) were prepared by plasma metallurgy method. Melted ingots were submitted to homogenization at 950 oC for 35 hours by means of vacuum high temperature furnace followed by furnace cooling under argon atmosphere. Subsequent heat treatment consisted of solid solution annealing at 900 oC for 1 hour under flowing argon with following water quenching. The phase analysis of the microstructure was performed using optical and scanning electron microscopies. The analysis was completed by EDX measurement that confirmed the β grains and α precipitates contained in the microstructure. Specimens of all three prepared alloys were subjected to microhardness testing to evaluate the influence of different thermal treatment. It was concluded that the solution treatment and water quenching promoted increase in the microhardness of Ti-12Mo-6Zr alloy whereas for developed Sn doped alloys the microhardness values remained the same.
