机械合金化工艺始于 196 6年 ,Ｂｅｎｊａｍｉｎ和他的合作者们用于制备氧化物弥散增强合金。近年来 ,机械合金化已被广泛地用于合成各种非平衡相 ,如非晶、准晶和纳米晶等。对于机械合金化导致非晶相的研究 ,近年来多集中于具有大的负混合热的二元系统。对于具有较小的负混合 The mechanical alloying process began in 1966 and Benjamin and his collaborators used to prepare oxide dispersion enhancing alloys. In recent years, mechanical alloying has been widely used in the synthesis of various non-equilibrium phase, such as amorphous, quasicrystalline and nanocrystalline. In recent years, the research on the amorphous phase caused by mechanical alloying has focused on binary systems with large negative heat of mixing. For smaller negative mix
