| Abstract: | Cu-2.3Ni-0.3Be-0.15Zr alloy was fabricated with Zr addition by non-vacuum smelting,and heat treatment for the alloy prepared was conducted to improve the mechanical properties. The properties of the alloy prepared were measured by hardness testing,electric conductivity testing and universal machinery testing. The microstructure was observed by OM(optical microscope) ,and the strengthening mechanism was introduced. The results show that cold deformation can promote the precipitation of new phase in the alloy... |
