摘要：

Cyclic deformation behavior of Cu single crystals with dispersed SiO2 particles were investigated. Even for a small amount of 0.41 vol.% dispersion of SiO2 particles, the cyclic deformation behavior was seen to be clearly different from that of pure Cu. There was longer life and slower clack propagation by the dispersion. This would be due to the homogeneous formation of the dislocation substructure in the Cu-SiO2 sample to prohibit the stress concentration at a point that fastens the clack nucleation.
