Hydrogen strengthening in niobium and niobium-base alloys

Conference ·
OSTI ID:4145290
This paper discusses solid-solution hardening, precipitate hardening, and alloy softening for Nb and Nb-base interstitial alloys. The effects of these strengthening mechanisms on strain rate sensitivity and ductility are also examined. It is shown that all three strengthening effects involve mainly interaction of dislocations with mobile hydrogen defects and are influenced or caused by residual interstitial solutes. (DLC)
