Abstract

The possibility of strengthening of VT1-0 titanium and Zr-1%Nb zirconium alloys by solid solution in rarefied controlled environment, oxygen containing, was shown. The impact of differences in partial pressure of oxygen on the gradient of strengthening nearsurface layers, weight gain and surface roughness of VT1-0 and Zr-1%Nb alloys was investigated.

Keyword(s): titanium-zirconium alloys, oxygen containing medium
