摘要
采用示差扫描量热、金相、透射电子显微镜及硬度测量等方法研究了微量Ｇｄ对互溶的ＡｇＡｕ系合金再结晶行为的影响。结果表明，在ＡｇＡｕ合金中加入微量（ｗＧｄ＝０２％）Ｇｄ后，在合金内形成含Ｇｄ的第二相颗粒，弥散分布于基体中，显著提高合金的再结晶温度，并使晶粒细化。随变形量增加，合金再结晶温度也随之提高。
The
influences of small content heavy rare earth element gadolinium on recrystallization in AgAu
alloys with mutual solubility were studied by differential scanning calorimetry, optical
microscopy, transmission electron microscopy and hardness measurement. It shows that in the
alloys which contain 02%(in mass fraction) Gd, there are dispersive second phase particles
formed by Ag, Au, and Gd. These particles result in increasing recrystallization temperature and
refining the grains of alloys. The recrystallization temperature of AgAuGd0.2 alloys increases
as the deformation increases. Small content Gd raises the apparent activation energy of AgAu
alloys.
