Effect of Cold Rolling Deformation on Aging Precipitation of Cu-Cr-Sn-Zn Alloy

The effects of different extent of cold rolling on the aging properties in Cu-Cr-Sn-Zn alloy are investigated by hardness and electrical conductivity analysis and microstructure TME (transmission electron microscopy) observation of the alloy. The results shows that dislocations provide nucleation site for precipitation during aging treatment, and result in the precipitation hardening effect from a finer size of precipitates. At 60% ratio of cold rolling and aged at 450℃for 1h, the hardness and electrical conductivity can reach 171.3HV and 71.5%IACS respectively.
