Microstructure and Resisting Thermal Shock Behaviors of TiC-Al_2O_3/Fe Functionally Graded Materials Prepared by SHS/PHIP

摘要

The microstructure and composition of TiC-Al_2O_3/Fe functionally graded materials (FGM) pre- pared by self-propagating high temperature synthesis and pseudo-hot isostatic pressing (SHS/ PHIP) were studied, and the resisting thermal shock behaviors were analyzed. The results show That TiC-Al_2O_3/Fe FGM has graded composition distribution. No cross-section crack through The layers was found in the tests of thermal shock and fatigue.
