摘要

利用行波电磁搅拌和低过热度浇注复合制备工艺成功地制备了A356半固态流变浆料。研究了浇注温度、搅拌功率和搅拌时间对A356铝合金的半固态浆料的影响。研究表明

该工艺可制备出符合流变成形所需的A356铝合金半固态浆料

浇注温度在液相线附近

搅拌功率越大

搅拌时间大于6s制备的A356半固态流变浆料中的初生α-Al越圆整

尺寸越细小。最佳工艺参数:搅拌温度为630℃

搅拌功率为1.2kW

搅拌时间为6s。

Abstract

Effects of pouring temperature

stirring power and stirring time on A356 aluminum alloy semi-solid rheological slurry prepared by the complex method of traveling-wave electromagnetic stirring and low super-heat were discussed.It is found that the prepared A356 Al alloy semi-solid rheological slurry by the complex method can meet the requirements of rheological casting.Primary α-Al in the semi-slid slurry is more and more round and its grain size is finer with increasing in stirring power in the conditions of stirring time more than 6 s and pouring at temperature near to liquidus temperature.The optimized processing parameters have been obtained including stirring temperature of 630 ℃ and stirring power of 1.2 kW and stirring time of 6 s.
