Description

technical field [0001] The invention relates to a titanium-aluminum-based powder metallurgy material mixed with boric anhydride particles and an application thereof, belonging to the technical field of powder metallurgy materials. Background technique [0002] Powder metallurgy takes metal powder (or a mixture of metal powder and non-metal powder) as raw material, and is an advanced process to manufacture metal, composite materials and various parts products through a series of processes such as powder mixing, pressing and sintering. Due to the high processing precision and easy size control of powder metallurgy products, especially in the production of complex-shaped parts, almost one-time molding can be achieved, which greatly reduces post-processing losses and has superior economic benefits. The composition ratio of powder metallurgy composite materials is easy to control, especially in the production of composite materials containing non-metallic powders, the powder segr...
