| Abstract: | Laves phase Cr_2 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 Cr_2 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. |
