Processing by Hydrostatic Extrusion of Titanium Coated with Aluminides

Abstract:

The material examined was commercially pure titanium with intermetallic Ti-Al layers produced by magnetron sputtering followed by glow discharge assisted treatment. This material was subjected to hydrostatic extrusion at room temperature. This resulted in substantial grain size refinement in the titanium accompanied by significant property improvement. The intermetallic Ti- Al layers reduced the pressure required during hydroextrusion and also increased the microhardness and frictional wear resistance of the material.
