【Abstract】 The effect of drawing deformation and heat treatment on the microstructure, mechanical properties and conductivity of Cu alloy materials has been investigated in the paper, and the strengthening mechanism has also been presented. The result shows that the material has high strength and good conductivity. Large quantity of second phase particles has precipitated after cold deformation and heat treatment. The grain size of Cu alloy gets smaller and its strength increases markedly due to the small grain size, dispersion strengthening and working hardening.更多还原
