摘要

采用蛇形通道浇注法制备半固态ZL101铝合金浆料

研究了浇注温度、弯道数量、冷却方式对半固态浆料组织的影响。结果表明

浇注温度在640

80℃范围时可获得理想的半固态ZL101铝合金浆料

其组织随浇注温度的降低

由蔷薇状向近球状或球状组织演变。在相同浇注温度下

弯道数量增加

可以改善初生α-Al晶粒的形貌

降低晶粒尺寸。弯道内的合金熔体具有"自搅拌"作用

使初生晶核演变为球状或近球状晶粒。

Abstract

The semi-solid slurry of ZL101Al-alloy was prepared by serpentine channel

and influences of pouring temperature

the number of curves and cooling ways on the microstructure of semi-solid ZL101 aluminum alloy were investigated.The results show that the satisfied semi-solid slurry of ZL101 aluminum alloy is prepared with pouring at 640℃to 680℃.The morphology of primaryα-Al grains is transformed from rosette to spheroid with the decrease of pouring temperature.At the given pouring temperature

increase of number of curves can improve the morphology of the primaryα-Al grains and decrease the grain size.The alloy melt exhibits the effect of"self-stirring"in the serpentine channel

which can make the primary nuclei gradually evolves into spherical and near-spherical grains.
