| The phase composition and microstructure, mechanical properties, electrical properties during deformation of AgCuZnNi alloy were analyzed. The results show that the AgCuZnNi alloy is mainly composed of silver-rich phase and copper-rich phase, Zn and Ni mainly exist in copper-rich phase. The displacement, rotation and broken of the copper-rich phase take place only when the deformation is small. With the increase of deformation, large particles of copper-rich phase first produce deformation, finally, all particles of copper-rich phase completely convert to fibrous tissue. Tensile strength and hardness increase with the increase of deformation, which attributed to the joint actions of deformation strengthening, grain boundary strengthening and fiber strengthening. Resistivity decreases with the increase of deformation, due to the increase of crystal defects and grain boundary. |
