摘要
文章通过对Cu0.69Cr0.13Zr合金铸锭进行热挤压、固溶、时效处理以及冷拉拔等工艺处理之后,通过对试样的抗拉强度、导电性能进行测试,并对不同工艺处理前后显微组织的变化进行观察对比,研究试样经不同处理工艺后的显微组织变化和抗拉强度及导电性之间的关系。研究发现,经960℃、0.5 h不完全固溶的Cu0.69Cr0.13Zr合金,铸造过程中形成的析出相能够在水封正挤的过程中形成纤维组织,该纤维组织在后续冷加工过程中得到进一步的纤维化和伸长;纤维组织的存在使Cu0.69Cr0.13Zr合金的强度由590MPa提高至690MPa,而导电率由80.0%IACS变为80.3%IACS。
The paper studied changes of microstructure and relationship between tensile strength and conductivity for Cu0.69Cr0.13Zr ingot which had been processed by hot extrusion, solution, aging and cold drawing. The results showed that after 960^） x0.5 h incomplete solution the precipitation phase generated from Cu0.69Cr0.13Zr alloy could form fiber texture in water-sealed forward extrusion of casting and the fiber texture enabled the strength of CuO. 69CrO. 13Zr to be improved from 590MPa to 690MPa, the conductivity from 80.0%IACS to 80. 3%IACS.
