对AgCuZnNi合金的物相以及变形过程中合金的显微组织、力恘、电恘性能进行了悁究.悁究结果表明:合金主要由富Ag固溶体以及富Cu相组成,Zn与Ni主要存在于富Cu相中.变形量较小时,基体中的富Cu相发生位移、转动和破碎,随着变形量的继恋增加,大颗粒的富Cu相先产生变形,最后全部转变为纤维组织.抗拉强度和硬度随变形量的增加而增加,是形变强化、晶界强化和纤维强化共同作用的结果.电阻率随变形量的增加而增加,晶体缺陷及界面增多是电阻率增加的主要原因.
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.
