摘要

试验研究了振动浇注和变质处理对ZL101合金气孔和组织的影响。结果表明

振动促进合金凝固过程中气体的析出

减少针孔的形成

改善铸件品质;振动具有细化晶粒、抑制柱状晶和枝晶生长、形成细小的等轴晶的作用;振动加变质的复合变质效果最好

铸件组织为等轴晶

晶粒细小。

Abstract

Effects of vibration casting and modification on gas holes and microstructure of ZL101 alloy were investigated.The results show that vibration can promote the gas precipitation in solidification process to decrease the formation of pinholes

improving the quality of ZL101 alloy.Vibration casting plays an important role in refining grain

restraining the growth of columnar crystals and dendrite and improving formation of fine equiaxed crystal.Modification combining with vibration casting exhibits the desirable effect

where fine equiaxed grain is dominant in the microstructure of the ZL101 alloy.
