Influences of Thermal Gradient and Solidus Velocity on Porosity Content in A201 Aluminum Alloy Castings
Abstract:
With systematic change in the riser size, together with variation of thickness and length, A201 aluminum alloys were cast in 100% silica sand molds. The higher the thermal gradient, the lower the porosity content was measured in the A201 aluminum alloy plate casting. And the faster the solidus velocity, the more the porosity content in this study. The porosity content of A201 aluminum alloy was influenced by both of thermal gradient and solidus velocity at same time in this study. Basically, high thermal gradient with slow solidus velocity seems get lower porosity content in A201 aluminum alloy castings.
