Study of Solidus Velocity on Porosity Formation in A201 Aluminum Alloy Castings

Abstract:

The purpose of the present study was to discuss the effects of solidus velocity on porosity formation of A201 aluminum alloy plate castings. With systematic change in the riser size, together with variation of thickness and length, were cast in sand molds. The sand molds with end chill for the plate castings were made of 100% silica sand. The porosity content of A201 aluminum alloy was affected by the solidus velocity in this study. The correlation between porosity content and solidus velocity is found to be split into 2 bands, each being associated with one of the different thickness of plate castings.
