摘要
对ＳＣＲ艺制得的２Ａ１１（ＬＹ１１）半固态坯料的重熔组织与成形性能进行了研究。实验证明，ＳＣＲ工艺２Ａ１１半固态坯料在 ５３０～５７０℃重熔温度范围内，合金组织优良，可进行半固态加工。ＳＣＲ工艺 ２Ａ１１半固态坯料半固态加工存在合理变形范围，进行半固态加工最大容许的变形范围为６４％～７２％。
Microsturctures and formation property of semi-solid 2A11 slab manufactured by SCR process are studied. It shows that under a certain remelting temperature scpoe from 530℃ to 570 ℃: formation property of alloy is fine, 2A11 can be formed in the semi-solid state. Semi-solid formation should be carried out within the proper deformation rate. The maximum deformation rate is 64% to 72%.
