采用WS-4型非自耗真空电弧炉熔炼制备了Ti-10Mo-6Zr-x Se(x=0,2,3,4wt%)合金系,并利用X射线衍射、金相显微镜、扫描电镜和能谱等手段研究了元素Se对其组织、物相和力学性能的影响。结果表明:该系列合金在加入元素Se后的晶粒显著细化,并且随Se含量增加,合金的晶粒尺寸呈减小趋势,由200μm左右减小到约20μm;元素Se加入后形成第二相,第二相以Zr-Se富集相的形式分布于晶界;在4%含量的Se加入后,Ti-10Mo-6Zr合金的室温抗压强度从1380MPa提高到1590MPa,屈服强度从1042MPa提高到1424MPa,同时压缩变形由12.1%降低至10.1%,降低幅度不大。
Ti-10Mo-6Zr-xSe (x = 0, 2, 3, 4wt%) alloy was prepared by melting with a WS-4 non-consumable vacuum arc furnace and characterized by X-ray diffraction, optical microscope, Spectroscopy and other means of element Se on the organization, phase and mechanical properties. The results show that the grain size of the alloy is significantly refined after the addition of elemental Se, and the grain size decreases with the increase of Se content, from about 200μm to about 20μm. The addition of elemental Se forms the second Phase and the second phase distributed in grain boundary in the form of Zr-Se enriched phase. The room temperature compressive strength of Ti-10Mo-6Zr alloy increased from 1380MPa to 1590MPa after 4% Se addition, and the yield strength increased from 1042MPa To 1424MPa, while the compression deformation decreased from 12.1% to 10.1%, the decrease is not large.
