Deformation and Fracture of P/M Titanium Alloys.
Abstract
Progress is reviewed for a research program whose primary purpose has been to provide a broad-based understanding of the deformation and fracture of high performance alloys in general and titanium alloys in particular. The research has ranged from strengthening mechanisms in titanium alloys to fundamental studies of crack propagation, localized necking, hydrogen embrittlement, and ductile fracture utilizing engineering alloy behavior. Progress for the period 1 July 1975 to 1 October 1984 is reviewed for the following portions of this research program: (1) the influence of silicon on the age hardening of beta-phase Ti alloys, (2) the flow and fracture behavior of multi-phase alloys with lamellar microstructures, (3) fracture along planar slip bands, (4) the multiaxial deformation and fracture of plastically anisotropic alloys in the form of sheet, (5) the influence of stress state on the hydrogen embrittlement of hydride-forming alloys in general and Ti in particular, and (6) the deformation and fracture of alloys containing pores and voids. Keywords: Ductile fracture, Crack growth, Porosity, Deformation, Hydrogen embrittlement, Age hardening, and Sheet metal deformation.
