Annual Technical Report to the Office of Naval Research.
Abstract
Progress is reviewed in a research program directed at the influence of microstructure (especially texture) and hydrogen on the deformation and fracture behavior of wrought alpha, alpha-beta and beta Ti alloys in the form of sheet and tubing under both uniaxial and multiaxial states of stress. Specifically, the research involves: (1) a study of the deformation and fracture of strongly textured Ti alloy sheet in: (a) uniaxial tension and (b) multiaxial tension, (2) an analysis of localized necking in sheet containing an imperfection inclined to the major principal stress axis, (3) the development of a fracture limit diagram for determining hydrogen embrittlement of sheet under multiaxial loading conditions, (4) a study of hydrogen embrittlement of Ti sheet under multiaxial deformation, (5) an examination of the effect of hydrogen on the multiaxial stress-strain behavior of Ti tubing, and (6) an initial effort to determine the sensitivity of a beta-phase Ti alloy, Ti-30V, to hydrogen embrittlement under multiaxial deformation.
