| Abstract: | Z]The microstructure of steel bonded carbide GJW35 after heat treatment has been analysed, and influence of the microstructure on the nucleation and propagation of thermal fatigue cracks of this alloy has been studied. The results show that the thermal fatigue cracks nucleate and propagate preferentially in the hard phase, and the nucleation and propagation are stoped by the steel based phase. By improving microstructure, the thermal fatigue resistance of this alloy can be raised. |
