Solidification Analysis and prediction of Shrinkage Cavity in Aluminum Alloy Castings
이영철Y . C . Lee, 이학주H . J . Lee, 홍준표C . P . Hong
Abstract
Solidification analysis of shaped castings and prediction of shrinkage cavity formation by the finite difference method were demonstrated with several examples. Several actual castings of aluminum alloy in sand mold wore experimented and the results were compared with those obtained by computer simulation. The two prediction parameters, temperature gradient and critical fraction solid for fluid flow, and an auxiliary parameter shrinkage potential, were adopted for predicting the formation of shrinkage cavity or porosity in aluminum alloy castings. It was found that a quantitative design of shaped castings can be made by the computer aided solidification analysis.
