摘要：

The present investigation attempts to evaluate the effect of ultrasonic treatment using water-cooled resonator on the microstructure and properties of different commercial Al-based alloys. The effect of ultrasonic treatment on the as-cast alloy microstructure can be summarized as follows: reduction of mean grain size, variation of phase distribution and better material homogeneity and segregation control. Ultrasonically treated samples have elongation values much higher than those obtainable with control processes. Our investigations confirm great advantages of ultrasonically treated ingots of hypereutectic AI-Si alloys upon deformation in semisolid state. (C) 1998 Elsevier Science B.V. All rights reserved.
