| 摘 要： | 提出了用粉末冶金法制备铜锰固溶体的方法 ,研究了铜锰粉末压坯的烧结特性。结果表明 ,利用粉末冶金法烧结铜锰混合粉末 ,可以形成单相固溶体 ,其扩散机理属于单向扩散 ,即锰进入了铜。随着烧结温度的提高和保温时间的延长 ,铜锰烧结压坯的密度和硬度都有下降的趋势。铜锰粉末经混料、预压、热压成型后 ,按不同烧结参数 (包括烧结温度和保温时间 )在 80 0℃烧结 ,保温 5 0h ,可制得铜锰固溶体。

| Abstract: | A method for making monophasic solid solution of copper and manganese by powder metallurgy process is presented. The sintering characters of green compact of copper and manganese powder are studied. The monophasic solid solution of copper and manganese is made by mixing, compacting and sintering copper-manganese powder. The diffusion mechanism belongs to unilateral diffusion, and the copper diffuses into the manganese. The densities and hardness of green compact sintered with copper-maganese powder decrease with the sintering temperature increasing and the heat preservation time prolonging. |
