研究了快速凝固Ａｌ－Ｃｒ合金的微观组织及显微硬度，确定了α－Ａｌ过饱和固溶体在退火过程中沉淀析出相为θ－Ａｌ７Ｃｒ，析出开始温度取决于过饱和度和沉淀位置．
The microstructure and microhardness of rapidly solidified binary Al-Cr alloy ststem has been studied.The beginning temperature of the second phase(θ-Al7Cr) precipitated from the supersaturated α-Al solid solution during annealing process seems to be determined by saturation and precipitation.Correspondent:Ml Guofa,(Ph.D student,Posi Box 434,Harbin Institute of Technology,Harbin 150006)
