STUDY ON EUTECTIC TRANSFORMATION IN Al-Cu ALLOYS UNDER 5 GPa PRESSURE CONDITION

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.
