摘要
Compression tests of Cu-2.2wt% Al, Cu-4.5 wt% Al and Cu-6.9 wt% Al with different stacking fault energy were carried out. The effect of stacking fault energy upon Cu-Al alloys has been investigated. Optical micrographs of the samples have shown the existence of deformation twinning. With the decrease of stacking fault energy, more deformation twins have appeared in the plastic deformation process of FCC metals. The appearance of the deformation twinning and the improvement of plasticity lead to the inhibition of deformation mechanism which is dominated by the dynamic recovery of alloy.
