The paper examines pressing of the titanium hydride powder in a die lubricated with adipose to produce pellets with H/d ≈ 4/1 and additional compaction of these pellets with a combined lubricant separating them from the die. The pellet extrusion pressure in the additional compaction process is one order of magnitude lower than when the powder is pressed in a lubricated die. This is indicative of drastic decrease in the external contact friction during additional compaction. Compaction of the titanium hydride powder mixed with a water-soluble organic lubricant has been experimentally studied.
