Summary:The semi-solid 6061 aluminum alloy castings with t’me equiaxed nondendritic grains are obtained by means of electromagnetic casting method.Appropriate casting technical parameters are casting temperature---720℃,casting speed---100 mm/min,cooling water amount---0.09 m3/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,itsσb is 392 MPa,vigid 142.3 HV andδ5 11.5%after T6 heat treatment.
