METHOD OF GAMMA-ALUMINIDE TITANIUM-BASED ALLOYS PRODUCTION Russian patent published in 2014 - IPC C22C14/00 B22F3/23 

FIELD: metallurgy.

SUBSTANCE: proposed process comprises production of the mix of powders, forming the pellet therefrom and execution of self-propagating high-temperature synthesis. Obtained the mix of pure metals containing titanium, aluminium, niobium and molybdenum in the following amount, it wt %: aluminium - 40-44, niobium - 3-5, molybdenum - 0.6-1.4, titanium making the rest. This pellet is compacted to relative density of 50-85% and subjected to thermal vacuum processing at 550-560°C for 10-40 min, heating rate of 5-40°C/ min and pressure of 10^-1-10^-3 Pa while SPS is performed at initial temperature of 560-650°C.

EFFECT: preset shape of casts, high mechanical properties.
