摘要
用示差扫描量热（ＤＳＣ），硬度测量等方法研究了无限互溶系统的Ａｇ－Ａｕ合金在Ａｕ含量小于５ｗｔ．％，溶质Ａｕ及不同变形量对该合金再结晶温度Ｔｒ的影响，并与有限固溶系统Ａｇ－Ｃｕ合金进行了比较。结果表明：Ａｕ对基体Ａｇ的再结晶有一定阻碍作用，但与Ｃｕ相比，这种作用小得多。变形量越大，Ａｇ－Ａｕ合金的再结晶温度越低。讨论了Ａｇ－Ａｕ合金的再结晶表观激活能，激活能随Ａｕ含量的变化与Ａｕ含量对再结晶温度的影响基本吻合。
The influences of solute Au and the degree of deformation on the recrystallization of silver-rich Ag-Au alloys have been studied by differential scanning calorimetry (DSC) and hardness measurement.Compared with Ag-Cu binary system with limited solid solution, the results show that the role of Au in retarding recrystallization of Ag matrix is smaller than Cu. The recrystallization temperature of Ag-Au alloys decreases as the deformation increases. The activation energy of recrystallization of Ag-Au alloys has been discussed. It is found that the change of the activation energy with the content of Au coincides essentially with the effect of Au content on the recrystallization temperature.
