摘要

采用自孕育法制备6061铝合金半固态浆料

对6061铝合金半固态流变压铸件微观组织进行了研究。结果表明

通过自孕育法可以制备出晶粒均匀细小且近球形的初生α-Al相半固态浆料组织。将自孕育法制备的半固态浆料经过短暂的保温后进行流变压铸

得到晶粒均匀细小的初生α-Al相组织。保温温度为640℃

保温时间为5min

压铸件初生α-Al相尺寸较小

圆整度较好

分别为65.7μm和1.27。

Abstract

The semi-solid slurry of 6061 wrought aluminium was prepared by the self-inoculation method

and the microstructure of rheo-diecasting 6061 wrought aluminium alloy was observed.The results indicate that the finer

uniform and nearly spherical primaryα-Al phase can be observed in semi-solid slurry by self-inoculation method.The slurry is held at the semi-solid temperature for a short time

then rheodiecasting.When slurry is held at 640 ℃for 5min

the primaryα-Al phase in die-casting has a smaller grain size of 65.7μm and a better shape factor of 1.27

respectively.
