Abstract:
The research progress on the brittleness of the Laves NbCr2 compounds at ambient temperature is sumarrized. The embrittlement mechanism and several methods of improving toughness of NbCr2 are mainly introduced, such as grain refinement, alloying and soft phase toughening. Finally, the existing problems in these researches are put forward and the future research fields are suggested.
