TITANIUM ENCAPSULATION STRUCTURE AND TITANIUM MATERIAL

摘要

A titanium encapsulation structure which is a titanium material provided with a packaging material formed from a pure titanium material, and a filler packed into the packaging material, the internal pressure of the packaging material being 10 Pa or less in terms of absolute pressure, and the filler being configured from at least one type of material selected from sponge titanium, titanium briquettes, and titanium scrap and having the same chemical composition as the pure titanium material. This titanium encapsulation structure makes it possible to manufacture a titanium material by hot working, and the conventional melting step and forging step can therefore be omitted.
