Abstract

An investment casting process utilizes rapid cooling during solidification to achieve a desired final microstructure. A molten high temperature aluminum alloy is poured into a ceramic shell mold. The ceramic shell mold is then lowered into an oil bath held in a quenching tank to rapidly cool the molten material. Thus, solidification takes place quickly via rapid extraction of the latent heat of the metal by the quenching oil bath. The rapid solidification achieves a uniform fine microstructure in an as-cast component.
