Abstract

This work describes a procedure utilised for predicting dendritic microstructure in the aluminium foundry process. Solidification of metallic alloys frequently results in a dentric microstructure which consists of a network of primary, secondary and tertiary branches. This procedure is based on the simulation of heat transfer during solidification associated with a relationship between thermal and microstructure parameters. An aluminium alloy containing 9.0wt% Si and 2.5wt% Cu was investigated. Initially, the dendritic microstructure was analysed by using the directional solidification technique. The objective of these experiments was to determine a relationship between dendritic growth and solidif
