Grain refinement of titanium alloys

摘要

A process for casting titanium alloy based parts includes the steps of 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 part.
