SWAGE CASTING OF A356 (AlSi7Mg0.3) ALLOY

Abstract

Swage casting, a new semisolid metal processing technology, has been developed in Balkan Center for Advanced Casting Technologies (BCACT) for manufacturing near-net shape components from leightweight metals. Components with one rotating axis such as a cylinder can be produced on a swage casting machine from molten metal in a one-step operation. The present study was undertaken to investigate the effect of intensive shearing action on the morphological evolution of as swage-cast A356 (AlSi7Mg0.3) alloy. Compared with conventional squeeze casting, the experimental results show that intensive melt stirring during swage casting, promotes the formation of net-globular and rosette-shaped grains.
