摘要
通过对低溶质Cu-Cr-Zr合金试样进行金相显微分析、透射电镜分析、能谱分析、X-射线分析及硬度测试,研究Cu-Cr-Zr合金的显微组织与性能,进而探索不同加工工艺及不同时效制度对Cu-Cr-Zr合金组织、硬度及高温氧化性能的影响.结果表明:固溶处理+冷变形+时效处理方式的强化效果最佳;在固溶度限度内,合金元素总量越多,合金硬度越高;合金元素的加入在表面形成了氧化膜,提高了合金的抗氧化性能.
The dilute solution alloy, namely Cu-Cr-Zr alloy, was analyzed by means of transmission electron microscope（TEM）, with energy dispersive X-ray spectrum, XRD. The hardness of Cu-Cr-Zr alloy was tested. The microstructure and the property of Cu-Cr-Zr alloy were analyzed. The influence that different treating methods and different aging processes to Cu-Cr-Zr alloy＇ s microstructure, hardness and high temperature oxidation was explored. The results indicated that the best process is solution treatment with cold work and aging. With the limit of bound of solution, the more the content of Cr and Zr, the higher the hardness of Cu-Cr-Zr alloy. The oxidation behavior of Cu-Cr-Zr alloy in high temperature to resist intenerating is improved. The oxide scale structure of Cu-Cr-Zr alloy improved the oxidation resistance of the alloy.
