摘　　要：研究了功率超声对半固态组织的作用,分析了超声波、施振温度的影响机制。结果表明,在功率超声作用下,A356铝合金半固态浆料组织明显细化,随着温度的升高,组织细化程度提高,但提高到一定程度时,细化效果减弱。The effect of power ultrasound on the organization of Semi-solid was investigated, and the mechanism about different temperature was analyzed. The results show that the effect of ultrasonic on the Semi-solid A356 grain can refine. With the increase of ultrasonic power, more refined structure can be obtained. However, when ultrasonic power is increased to a certain degree, the effect of refining grains is deceased.
