摘要

研究了3组半固态坯料断面的组织特征。结果表明

通过坯料切口断面的宏观、微观特征

可以粗略地判断制备浆料的初生相的基本形态

大小和分布特征。合金熔体未经过处理的浆料组织

初生晶粒呈粗大的等轴晶团簇和粗大的枝晶形态

大小不一

分布不均匀;合金熔体经过螺旋线槽处理后的浆料组织

初生晶粒呈相对细小的均匀分布的球晶或近球晶形态。

Abstract

Three groups macro-micro characteristics in the cross section of A356semi-solid slurry incision were observed.The results show that the basic morphology

size and distribution of primary phases in the slurry prepared can be evaluated roughly through the characteristics in the cross section of the incision.The primary grains in untreated alloy melt present coarsening equiaxed grain and dendrite with varied size and uneven distribution.The primary grains in alloy treated through the helical curve duct present more tiny uniform distributed spheroidization or nearly spheroidizaed morphology.
