Abstract

See full text

A casting method for titanium and titanium alloys, the casting method including obtaining an investment casting mold composition having calcium aluminate and aluminum oxide, the calcium aluminate combined with a liquid to produce a slurry of calcium aluminate, and wherein the solids in the final calcium aluminate/liquid mixture with large scale alumina is about 71% to about 90%. The method further includes pouring the investment casting mold composition into a vessel containing a fugitive pattern, curing the investment casting mold composition to form a mold, removing the fugitive pattern from the mold, firing the mold, preheating the mold to a mold casting temperature, pouring molten titanium or titanium alloy into the preheated mold, solidifying the molten titanium or titanium alloy and forming a solidified titanium or titanium alloy casting, and removing the solidified titanium or titanium alloy casting from the mold.
