Abstract—

This work investigates the formation of an ordered Ti₃Al phase (α₂ phase) in Ti–Al alloys as a function of the time and aging temperature. High-temperature treatment performed in the single-phase α field and the subsequent aging at different temperatures have been shown to result in more intense precipitation and growth of disperse particles than that resulted from pretreatment in the β field. The formation of a martensite structure during quenching complicates the subsequent transformation by the homogeneous mechanism.

Ti-17 at％Al合金中两相（α+α2）结构形成的特征

摘要—

这项工作调查形成一个有序的Ti ₃ Al相（α ₂按Ti-Al系合金相）作为时间的函数，并且老化温度。与在β场中进行预处理相比，在单相α场中进行的高温处理以及随后在不同温度下的老化已显示出导致分散颗粒更强烈的沉淀和生长。淬火过程中马氏体结构的形成使随后的均质机理相变复杂化。
