摘要

采用水冷铜质蛇形通道制备了半固态A380铝合金浆料

研究了浇注温度、弯道数量、冷却水流量对半固态A380铝合金浆料组织的影响。结果表明

随着浇注温度的降低

初生α-Al晶粒尺寸减小、形状因子提高;浇注温度在610

30℃时

可以获得理想的半固态浆料组织。随着水冷铜质蛇形通道弯道数量增加

半固态浆料组织中初生α-Al晶粒更加细小、均匀、圆整。水冷铜质蛇形通道冷却水流量为500L/h时

可以获得初生α-Al晶粒细小、圆整的半固态浆料组织。

Abstract

The semi-solid slurry of A380 aluminum alloy was prepared by a water cooling copper serpentine pouring channel

and influences of pouring temperature

the number of curves and the flow of cooling water on the microstructure of semi-solid A380 aluminum alloy slurry were investigated.The results demonstrate that grain size of the primaryα-Al is decreased and its shape factor is increased with the decrease of pouring temperature.Satisfied semi-solid slurry was prepared with pouring at 610 ℃ to 630℃.With the increase of number of curves

the primaryα-Al grain size in the semi-solid slurry can be refined with more homogeneous distribution and spheroidization.When the flow of cooling water reaches500L/h

the microstructure of semi-solid slurry become finer and more spherical.
