摘要
采用水冷铜坩埚真空感应熔炼技术制备了名义成分为Ti-12Nb-12Zr-2Mo(质量分数,%)的合金,对获得的样品在真空热处理炉中进行热处理。采用X射线衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)以及力学测试等技术对铸态和热处理后得到样品的显微组织和力学性能进行系统研究。结果表明:铸态和退火状态下合金的组织均由α和β相组成,淬火状态下合金组织由α′和β相组成。热处理有利于提高合金的强度,而不改变合金的弹性模量。
Ti-12Nb-12Zr-2Mo （wt%） alloy was prepared was conducted using a vacuum furnace. Microstructure by a water jacketed copper crucible induction melting furnace. The heat treatment and mechanical properties of as-cast and heat treated alloy were investigated by XRD, SEM, TEM and mechanical test. Results show that microstructure of both the as-cast and the annealed alloy is composed of a and β phase, while that of the quenched alloy is composed of α＇ and β phase. Heat treatment is conductive to improve the strength while it changes the elastic modulus slightly
