一种Ti-Mo-Nb-Al合金的固溶态显微组织研究

Microstructure of the Alloy Ti-Mo-Nb-Al after Solution Treatment

通过对金相显微组织观察、X射线衍射和透射电镜分析 ,研究了 Ti- Mo- Nb- Al合金在不同固溶温度淬火后的组织和相变规律。结果表明 :该合金在相变点以下的淬火组织由α,β相和淬火ω相及 Ti5 Si3相组成 ,随温度升高 ,α相减少 ;在相变点以上的淬火组织为β相和少量淬火ω相及 Ti5

The influence of solution treatment on the phase transformation and microstructure of the alloy Ti Mo Nb Al is studied. The phase transformation and microstructural characterization of this alloy after different solution treatments are analyzed using optical and transmission electron microscopies(TEM),and X ray diffraction(XRD)technique.
