Effects of Zn Content on the Grain Growth Law of Ag-Cu-Zn Alloys

摘要:

对不同Zn含量的Ag-Cu-Zn合金在不同温度、不同热处理时间的晶粒长大规律进行了研究。研究结果表明，随着保温时间的延长，晶粒逐渐长大。在相同保温时间下，Zn含量越高，晶粒长大越明显。随着Zn含量增加，晶粒长大指数n逐渐增大，晶粒长大的激活能Q逐渐降低

Abstract:

Grain growth behaviors of Ag-Cu-Zn alloys with different contents of Zn were studied at various heat treatment temperatures and for different holding time. The experimental results show that the grain grows along with the increase of the holding time. The higher the content of Zn is，the larger the grain size will be under the same holding time. The grain growth exponent n increases and the grain growth active energy Q decreases with the increase of the content of Zn
