采用硬度测试、金相显微镜、X射线衍射、扫描电镜、透射电镜和能谱分析技术,研究热处理工艺对V55Ti30Ni15合金组织和硬度的影响.不同热处理温度和时间下的合金显微组织对合金硬度有很大影响.研究结果表明:铸态合金由过饱和钒基固溶体以及非平衡的NiTi和NiTi2相组成.合金在750和800℃热处理时,细小NiTi粒子从过饱和钒基固溶体中析出,随着保温时间延长,NiTi粒子析出增多.NiTi粒子析出降低了钒基固溶体的晶格畸变度,合金硬度降低.合金在850和900℃热处理时,NiTi析出粒子逐步回溶到钒基固溶体中,晶格畸变度升高,合金硬度升高.在900℃热处理初期,合金硬度下降是由于铸造应力的消除,晶格畸变度降低.而随后由于NiTi2相在相界上聚集球化,使得合金的硬度开始升高.
