Powell, G L; Northcutt, Jr, W G

Internal hydrogen embrittlement of U-5.7Nb alloy is manifest by an enhanced microvoid coalescence fracture mode and a loss in tensile ductility for hydrogen concentrations below 20 ..mu..g/g. At higher concentrations, i.e., 36 ..mu..g/g, very low ductilities and brittle fracture modes are observed along with evidence for hydride formation.
