Abstract
The Ti-10Zr-5Mo-xSn alloys were molten in the non-consumable electric arc furnace. Influences of Sn on the phases,
microstructures and correlative mechanical properties of Ti alloys have been analyzed by use of X ray diffractive
instrument(DX2000-), optical microscope (4XC-) for metallography, sclerometer (HV-50A) and machine for abrasion(M-200).
It was found that Ti-10Zr-5Mo-xSn alloys were composed of equiaxed α phase. Moreover, with the increase of Sn,
diffractive peak of α′′ phase began to appear and peak intensity increased gradually, and Sn could stabilize β together with
Mo during annealing process. Furthermore, the addition of Sn could improve the hardness (HV) and abrasion resistance.
