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

摘要:

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雀火后的组织和相变规律。结果表明：该合金在相变以下的淬火组织由α，β相和淬火ε相及Ｔｉ５Ｓｉ３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相和少量淬火相及Ｔｉ５Ｓｉ３相。

Abstract:

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.
