Title:
BAFFLES, SUPPRESSORS, AND POWDER FORMING METHODS
Document Type and Number:
WIPO Patent Application WO/2017/131867
Kind Code:
A3
Abstract:
A method of forming a titanium aluminide product includes preparing a titanium aluminide powder system, forming the titanium aluminide powder system into a green shape, sintering the green shape to create a sintered product, and deoxygenating the sintered product to form the titanium aluminide product. Oxygen content of the titanium aluminide product may be below 600 weight ppm or 200 weight ppm. Deoxygenating may be by deoxidation in solid state (DOSS) or molten salt electrolytic methods. Forming may be through one of compaction and powder metal injection molding. The method may also include machining.
