摘要

采用自制的V型对向式双振动头功率超声处理装置

研究了熔体浇注温度和流道倾斜角度对5083合金半固态组织细化规律的影响。结果表明

功率超声对5083合金组织有明显的细化作用;流道倾角一定时

晶粒尺寸和形貌随着浇注温度的提高（试验所选范围）而变得细小和均匀;5083合金组织在流道倾角为20°时细化效果最佳。

Abstract

we have developed a V-shaped subtended double power ultrasound vibration heads treatment device to understand effects of pouring temperature and inclined angle of flow channel on the microstructure refinement of semi-solid 5083 alloy.The results show that power ultrasound can refine significantly microstructure of 5083 alloy structure.With a fixed inclined-angle

the grain size and morphology are refined with uniform distribution in the alloy with increasing in pouring temperature（the selected range of experiment）.In addition

with the inclined angle of 20° which is selected in three pouring angle（10°

20°

30°）

the desirable refinement in microstructure of 5083 alloy can be observed.
