Impact of grain refining on semisolid metal processing

Abstract

Desired microstructure for semi solid metal (SSM) processing contains primary particles free of dendrites and almost in the globular form with minimum entrapped eutectic. The crucial matter is the form and size of primary particles and more spherical and lesser size give better flowability during component shaping process with the added additional benefit of superior mechanical properties. In this study, with simultaneous conventional and SSM processing of aluminum alloys, most important and critical parameters for refiner employment will be explained.
