Nondendritic Microstructure of 6061 Alloy Obtained by Electromagnetic Casting and Thixoformed Properties

摘要：

　　The semi-solid 6061 aluminum alloy castings with fine equiaxed nondendritic grains are obtained by means of electromagnetic casting method.Appropriate casting technical parameters are casting temperature---720℃,casting speed---100mm/min,cooling water amount---0.09m3/min.The temperature field in the electric stove reheated to the liquid-solid zone is homogeneus and the prope reheating temperature is 630℃.When the mould temperature is 300℃-500℃,the parts used in automobiles can be thixoformed successfully,its σb is 392MPa、vigid 142.3HV and δ5 11.5% after T6 heat treatment.
