机械合金化的研究进展

机械合金化(MA),作为制备合金粉末的一种高新技术,使过去用传统熔炼工艺难以实现的某些物质的合金化和远离热力学平衡的准稳态、非平衡态及新物质的合成成为可能.MA技术引起了材料科学界的广泛关注.综述了近年来机械合金化在理论模型和固态反应方面的研究情况,详细介绍了MA技术在制备弥散强化合金、金属间化合物、功能材料和亚稳材料(包括非晶、准晶、过饱和固溶体、纳米晶等)中的应用进展,展望了机械合金化的发展趋势.

Progress in Studies on Mechanical Alloying

Mechanical Alloying(MA),as one of the high techniques on preparing alloy power,made it possible to alloy some materials which can not be realized with the traditional melting craft in the past.Meanwhile,the quasi-stable state and non-equilibrium state which are far from thermodynamic equilibrium and the synthesis of new materials can be realized.The technique of MA caused extensive concern in the material science field.With MA technique,the research in recent years on theory models and solid-state reactions were summarized.The applying progress of the MA technique in preparing materials such as dispersion strengthened alloy,intermetallics,function material and metastable materials(including non-crystal,pseudo crystal,supersaturated solid solution and nano-crystal) are detailed,and the development trend of the MA technique is prospected.
