AGING PRECIPITATION OF Cu-Zr AND Cu-Zr-Si ALLOYS AND AFFECTED BY COLD WORKING
Cu-Zr和Cu-Zr-Si的时效析出特性及冷变形对时效析出的影响

The hardness and electric conductivity of Cu-Zr, and Cu-Zr-Si alloys varied withdifferent aging regimes were measured and the factors influencing the electric conductivity wereanalyzed. It is believed that a little Si can fine the precipitates and better the resistance tosoften. The improvement of material properties by aging and the effect of cold work were alsodiscussed.
