Effect of Cyclic Condition on Thermal Shock Crack Propagations of YG20 Cemented Carbide

  • The effect of cyclic condition on thermal shock crack propagations are studied.The results show that the incubation period of crack decrease with the raise of cyclic temperature and the increase of cooling rate.There are fatigue stripes on the thermal shock sample fractures.
