EFFECT OF DEFORMATION PROCESSING ON THE PROPERTIES AND STRUCTURE OF TITANIUM OBTAINED BY PLASTIC DEFORMATION OF HYDROGEN-ALLOYED TITANIUM SPONGE

The effect of hydrogen alloying of titanium sponge on the properties of compacted preforms is experimentally investigated at 170 °C, 325 °C under a pressure 1000 of MPa. The influence of the density of the preforms and the presence of hydrogen in them on the force of direct extrusion at a temperature of 600 ºC, the density and mechanical properties of extruded bars has been revealed.

The results show the expediency of using the effect of hydrogen plasticization in manufacturing quasi-monolithic preforms from noncompact raw materials in the form of titanium sponge by plastic forming.
