摘要

通过电磁搅拌制备半固态A356铝合金熔体

利用正交试验研究了工艺参数对半固态A356铝合金熔体固相率和形状因子的影响。结果表明

保温温度对固相率的影响最为显著

输出电压和搅拌频率的影响次之;输出电压对形状因子的影响最为显著

搅拌频率次之

保温温度的影响最弱。随着保温温度的增加

固相率降低;随着输出电压、搅拌频率的增大

形状因子越接近1

即晶粒形貌越接近球状。

Abstract

Semi-solid A356 aluminum alloy melt was prepared by electromagnetic stirring process

and influences of processing parameters on solid fraction and shape factor of semi-solid A356 aluminum alloy melt were investigated by orthogonal experiment method.The results show that factors influencing solid fraction is presented as follows:holding temperature

output voltage and then frequency;factors affecting shape factor is output voltage

stirring frequency and then holding temperature.With the increase of holding temperature

the solid fraction is decreased

while with the increase of output voltage and stirring frequency

the shape factor tends to 1

which means the grain morphology closed to being spherical.
