    摘要:

    非晶合金具有优异的力学性能、耐蚀性、磁性能等,是一种具有极大应用潜力的新型结构材料和功能材料,然而传统方法制备的非晶合金受“临界冷却速度”的影响,有尺寸上的限制,制约了非晶合金的应用范围。而放电等离子烧结(Spark Plasma Sintering,SPS)制备的非晶合金不受 “临界冷却速度”的影响,可以制备出较大尺寸的非晶合金。本文主要从致密化机理、工艺影响因素、性能对比、数值模拟等方面介绍了放电等离子烧结制备非晶合金的研究现状,分析了其难点及以后的发展方向。

    Abstract:

    Amorphous alloys possess excellent mechanical properties, corrosion resistance, and magnetic properties, and are a new structural and functional material with significant application potential. However, the preparation of amorphous alloys via traditional methods is restricted by the critical cooling rate, and the forming size is also limited; these factors restrict the application of amorphous alloys. However, the preparation of amorphous alloys via spark plasma sintering (SPS) is not limited by the critical cooling rate, and SPS can therefore produce larger amorphous alloys. This paper summarizes the research progress of the preparation of amorphous alloys via SPS from the aspects of the densification mechanism, process parameters, comparative study of properties, and numerical simulation, and analyzes its difficulties and future development directions.
