Mechanical Properties and Porosity Content of A201 Aluminum Alloy Castings in Different Cooling Rate Sand Molds

Abstract:

Article Preview

A201 aluminum alloy plate castings with systematic change in the riser size, together with variation of thickness and length, were cast in different kinds of molds to find out the influence of cooling rate on the mechanical properties and porosity content. The sand molds with end chill for the plate castings were made of 100% silica sand (type A mold), 50%silica sand/50% chromite sand (type B mold) and 100% chromite sand (type Cmold). Both the porosity content and mechanical properties of A201 aluminum alloy plate casting are governed by the cooling rate. Both of tensile strength and elongation are reduced when the porosity content becomes more.
