摘要

在ZL114A熔体浇注过程中施加超声振动

研究超声波功率对合金致密度的影响。结果表明

超声波功率大小对ZL114A合金的组织细化和致密度提高效果明显。随着超声功率增加

试样的致密度提高

当超声施振功率提高到600 W时

合金的致密度达到峰值0.9986

此后随着功率增大

合金致密度有下降的趋势。通过金相组织观察分析

发现超声波的空化作用及声流作用可以细化晶粒、减少缩孔、缩松

从而提高凝固组织致密度。

Abstract

Effects of ultrasonic power on relative density of the ZL114 Aalloy were analyzed by applying ultrasonic vibration in the process of ZL114 A melt.The results indicate that the ultrasonic treatment plays the remarkable role in refinement of microstructure and increase of relative density of the ZL114 A alloy.The relative density is increased to 0.998 6with the increase of ultrasonic power to 600 W.However

with further increases of the ultrasonic power

relative density of the ZL114 Aalloy is decreased gradually.The microstructure observation reveals that cavitation and acoustic streaming effect of ultrasound power can refine grain size and reduce the porosity shrinkage to improve the sound solidification microstructure of the alloy.
