5 GPa压力条件下Al-Cu合金的共晶转变
STUDY ON EUTECTIC TRANSFORMATION IN Al-Cu ALLOYS UNDER 5 GPa PRESSURE CONDITION
摘 要
通过对Al-25 %Cu和Al-45 %Cu合金在5 GPa压力条件下组织凝固的研究,测得了Al-Cu合金在5 GPa压力条件下的共晶点,结合H. M. Kagaya等确定的相同压力条件下Al-Cu合金的固溶度曲线,给出了Al-Cu合金在5 GPa压力条件下部分相区的示意相图。

Abstract
Eutectic transformation point of Al-Cu alloys solidified under 5 GPa pressure condition had been determined through the microstructures study. Phase diagram of the Al-Cu alloys had been drawn combined with the results on solidus of Al-Cu alloys by H. M. Kagaya under the same pressure condition.
