PROBLEM TO BE SOLVED: To further refine Ti-based alloys to produce a final microstructure of fully refined transformed beta grains or a duplex microstructure with refined transformed beta grains and fine primary alpha grains.;SOLUTION: A process for casting titanium alloy based parts comprises melting a quantity of titanium alloy to form a molten titanium alloy; adding to the molten titanium alloy a quantity of boron in an amount of about 0.2 weight percent to about 1.3 weight percent of the molten titanium alloy to form a molten boron modified titanium alloy; and casting a boron modified titanium alloy based parts.;COPYRIGHT: (C)2008,JPO&INPIT
