采用非自耗电弧炉制备了Ti-xZr-5Mo合金

利用X射线衍射仪、倒置金相显微镜、维氏硬度计、磨损试验机

测试并分析了Zr元素对合金的相结构、显微组织、硬度（HV）和磨损性能的影响。结果表明

Ti-xZr-5Mo合金主要由等轴的α晶粒组成

随着Zr含量的增加

合金中α相比例增大

但在慢速冷却过程中

Zr可以和β相稳定元素（Mo）一起

稳定β相至室温

使得退火后合金β相比例增大;且随着Zr含量的增加

合金的硬度（HV）值、耐磨性均显著提高。

Effects of Zr element on phase structure

microstructure

Vickers hardness and wear resistance of Ti-xZr-5Mo alloy prepared by non-consumable electric arc furnace were analyzed by XRD（X-ray diffraction）

4XC upside-down microscope for metallography

HV-50A sclerometer and M-200 abrasive machine.The results reveal that Ti-xZr-5Mo alloy is mainly composed of equiaxed α phase

and equiaxed α phase is increased with increasing in Zr content.However

β phase is increased in the annealed alloy during slow cooling rate

which is attributed to Zr element and Mo element stabilizing β phase to room temperature.Meanwhile

with increasing in Zr content

hardness and wear resistance of the alloy are greatly improved.
