Chemical and mechanical interactions of interstitials in V-5%Cr-5%Ti
- Oak Ridge National Lab., TN (United States)
Gas-metal reaction studies of V-5Cr-5Ti were conducted to determine the kinetics of reactions with H{sub 2} and O{sub 2}, respectively, at 400-500{degrees}C. Reaction rates were determined through weight change measurements and chemical analysis, and effects on mechanical properties were evaluated by room temperature tensile tests. Exposure to hydrogen at pressures between 10{sup {minus}4} to 10{sup {minus}2} torr lowered the tensile ductility in the case of coarse-grained specimens but had little effect on finer-grained specimens. Similarly oxygen uptake at 500{degrees}C, at concentrations as low as 200 ppm (by weight), significantly lowered the ductility of the coarser-grained but not the finer-grained material.
