The microstructure and hardness of copper alloy after fatigue-creep interaction
testing have been investigated. Experiments were carried out in the temperature
range from room temperature to 300oC. Attention has been paid to the role of the
microstructure and hardness on the fatigue-creep strength of copper alloy. It has
been shown that, there is a little effect of microstructure in the cyclic response of
copper alloy, while the hardness has a significant effect on the fatigue-creep
strength. The relation between strength and hardness were described by the
following equation:
σE.L. = 5.345 H0.6217
