  • BAFFLES, SUPPRESSORS, AND POWDER FORMING METHODS
    Publication number: 20190212090
    Abstract: A method of forming a firearm suppressor baffle including preparing a titanium alloy powder system, forming of the powder system into a green shape, optionally green machining the green shape, sintering the green shape to create a firearm suppressor baffle formed from sintered material, where the firearm suppressor baffle has an elevated oxygen content of between 0.2 and 0.5 weight percent. The resultant sintered material may have a creep value of less than 1.5% at 50 hours at 450 C. Also, a method of forming a firearm suppressor baffle including preparing a titanium aluminide powder system, forming the titanium aluminide powder system into a green shape through one of compaction and powder metal injection molding, and sintering the green shape to create the firearm suppressor baffle. The titanium aluminide powder method may also include deoxygenating the firearm suppressor baffle. Also disclosed are baffles and suppressors formed using these methods.
