Abstract
The addition of oxygen to a Nb-10 at. pct V alloy results in linear hardening and an increase in the strain rate sensitivity with increasing concentration. Hydrogen induces a minimum in the reduction of area, a temperature dependent hardening, and a maximum in the strain rate sensitivity of Nb-10V at ≈150 K. The strengthening and accompanying low temperature softening by hydrogen below 150 K are explained by a strain-induced ordering of hydrogen atoms around dislocations. Indications are, however, that hydrogen interacts only weakly, if at all, with the oxygen. A ductility minimum and associated return-of-ductility due to hydrogen are attributed to the high strain rate that occurs in the necked region during deformation.
