Abstract
The invention relates to a process for the removal of oxides and/or oxygen which are formed on the surface of the casting during the investment casting process to levels that are comparable to those found within the bulk of the metal casting thus reducing the inherent hardness of the surfaces of the casting. More specifically, the invention relates to a process for removing oxide layers from titanium casting using an alkaline earth deoxidizing agent.
