Fatigue crack initiation in powder metallurgically-processed tool steel material under cyclic loading / Al Emran Ismail and Mohd Nor Berhan

The cyclic behavior of P/M steel has been evaluated at different tempering conditions. Heat treatment is found to significantly affect the hardness, micro structure and fatigue response of the material. Optimum tempering temperature is found to give the highest hardness and better fatigue life compa...
