摘要/Abstract

摘要： 高熵合金是近年来涌现出的一种新型合金,突破了以一种或者两种元素为主、少量添加元素为辅的传统合金设计理念。作为高熵合金体系一个重要分支—FCC结构的高熵合金,具有高损伤容限、良好的抗辐照能力、高耐磨、耐腐蚀性能等一系列优异的性能,可以作为理想的工程结构材料。然而,FCC结构高熵合金强度-塑性不匹配严重制约了其工程应用。研究表明,析出强化可以有效提高FCC结构高熵合金的强度,产生优异的强度-塑性匹配性能,各国学者相继开发出大量的高性能析出强化高熵合金体系。本文主要介绍了FCC结构高熵合金的析出强化研究,包括非共格析出相和共格析出相,着重介绍了研究现状以及强韧化的影响机制,并对未来高熵合金析出强化研究进行了展望。

Abstract: High entropy alloys (HEAs) are a new kind of alloys,which break through the traditional alloy design with one or two elements as principal constituent and a few elements as auxiliary constituent.As an important branch of high entropy alloy system,FCC structure HEAs show excellent properties,such as high damage tolerance,good irradiation resistance,high wear resistance and corrosion resistance.However,the strength-ductility tradeoff dilemma of FCC structure HEAs severely limits their engineering applications.Previous researches indicate that precipitation strengthening can effectively improve the strength of FCC structure HEAs and produce excellent strength-ductility synergy properties.The research progress on precipitation strengthening of FCC structure HEAs was mainly introduced,including incoherent and coherent precipitates.The current research status and underlying influence mechanisms of precipitation-strengthening were briefly reviewed.The future prospective of precipitation-strengthening in FCC structure HEAs was also discussed.

Key words: high-entropy alloy(HEA), FCC structure, precipitation strengthening, strength-ductility synergy properties
