Effect of Phase Composition and Deformation Conditions on the Hydrogen Plasticization of Hydrogen-Containing Titanium Alloys

摘要

The effect of hydrogen as an alloying element on the plastic-deformation characteristics of commercial titanium and Ti-6Al and Ti-6Al-4V alloys is studied. A relation between the strain resistance of the alloys and their phase composition is established over a wide temperature range. The parameters of the hydrogen hardening of the alloys in the single-phase beta field and hydrogen plasticization conditions are determined.
