Abstract

Aluminium based metal matrix composites are finding wider usage in most of the engineering applications owing to their excellent mechanical properties. These composites are prepared by liquid metallurgy route. The quality of castings produced by this method largely depends on the rate of cooling during the solidification of the composite melt. It is therefore, very much essential for the foundry technologists to understand the solidification phenomenon and control the influencing variables resulting in sound quality castings. In the present work, casting simulation is carried out for LM25 aluminium alloy and its silicon carbide particle composites using commercially available CASTDESIGNER™ software. The simulated cooling curves are experimentally verified and found to be in good agreement.
