本文以氢化物的形式在ＦＥ和Ｔｉ元素混合粉机械合金化过程中引进氢原子。利用ＸＲＤ，ＴＥＭ，ＤＳＣ等实验手段探讨了氨原子对固态合金化和结构的影响，以及氨化物的分解过程。研究结果表明崐ＴＨ２，氢化物在机械合金化过程中按以下过程分解：ＴｉＨ２→ＴｉＨ１．→ＴｉＨ→ａ→Ｔｉ。分解的氢原子导致亚稳过渡扣βＴｉ的形成。Ｆｅ与企稳过波相β－Ｔｉ固态反应生成非品ＦｅＴｉ相，同时氢原子也促使已形成的ＦｅＴｉ相进一步转变为非晶相 In this paper, hydrogen atoms are introduced in the form of hydride during mechanical alloying of FE and Ti elements. The effects of ammonia on solid-state alloying and structure, as well as the decomposition process of amides, were investigated by means of XRD, TEM and DSC. The results show that Kun 2, hydride decomposition in the mechanical alloying process according to the following process: TiH2 → TiH1. → TiH → a → Ti. The decomposed hydrogen atoms lead to the formation of metastable transition βTi. Solid-state reaction of Fe and stabilized β-Ti phase produces non-product FeTi phase, and hydrogen atoms also promote the further transformation of the formed FeTi phase to amorphous phase
