超声波对合金结晶过程的均匀化作用

The Homogeneity of Casting Alloy Process Effected by Ultrasonic

在铸造合金中导入超声波，其周期性的空化和搅拌作用，使合金液的温度和成分均匀化，细化了铸造组织，减轻了铸造合金的宏观偏析倾向。

The ultrasonic leading in casting alloy liquid with periodity empting and agitation effect,make homogeneity of temperature and composition of casting alloy liuid,refine casting alloy microstructure,weaken macrostructure segregation of casting alloy.
