METHODS FOR PRODUCING TITANIUM AND TITANIUM ALLOY ARTICLES
摘要
A method of producing an article selected from a titanium article and a titanium alloy article comprises melting feed materials with a source of hydrogen to form a molten heat of titanium or a titanium alloy, and casting at least a portion of the molten heat to form a hydrogenated titanium or titanium alloy ingot. The hydrogenated ingot is deformed at an elevated temperature to form a worked article comprising a cross-sectional area smaller than a cross-sectional area of the hydrogenated ingot. The worked article is dehydrogenated to reduce a hydrogen content of the worked article. In certain non-limiting embodiments of the method, the dehydrogenated article comprises an average a-phase particle size of less than 10 microns in the longest dimension.
