摘要
对二元Ａｌ－１０ｗｔ％Ｃｕ亚共晶和Ａｌ－３３．２ｗｔ％Ｃｕ共晶合金液态进行７００～１２００℃范围过热处理，然后在粘土砂型和金属型中凝固。试验研究了液态过热对固态显微组织、显微硬度、宏观晶粒大小及凝固过程特征温度的影响，分析了Ａｌ－Ｃｕ合金的液态结构。
he Liquids of binary Al-10wt%Cu and Al- 33.2wt%Cu alloy have been performed superheating treatmenting in the range 700～1200℃,then solidfied in sand and metal mould The influences of super-heating on the microstructure,micro hardness grain size and thermal analysis of solification have been studied.The structure of liquid Al-Cu alloy has been analysed.
