摘要
综述了Laves相Cr_2Nb金属间化合物的结构和变形机制及其韧化研究进展,重点评价了细晶增韧、软第二相增韧和合金化增韧这三种方法,指出了存在的问题及今后的研究方向。
Laves phase Cr2 Nb is a potential high temperature structural material for areo-engine applications. This paper reviews the progresses in current researches on structure, deformation mechanism and toughening of Laves phase Cr2 Nb intermetallic compounds. Three toughening methods, namely fine grain toughening, soft second phase toughening and alloying toughening, are surveyed emphatically. Furthermore, some existing problems and future inves- tigation directions are suggested.
