Deformation and Fracture of P/M Titanium Alloys.
Abstract
Progress is reviewed for a research program which is examining selected processing-microstructure-property relationships which limit the mechanical properties of P/M Ti alloys in particular and aspects of ductile fracture in general. The approach is quite broad and ranges from experimental and analytical studies of the effect of porosity on the fracture of engineering alloys to be an experimental examination of the hot isostatic pressing of metallic powders. Progress for the period 10/1/82-9/30/83 is reviewed for the following aspects of this research program: the tensile deformation and fracture of alloys containing porosity; experiment and modeling of P/M titanium alloys; the influence of strain-rate on the flow and fracture behavior of titanium and nickel containing porosity; a modeling study of the influence of void distributions on the mechanism of ductile fracture; hot isostatic pressing of metallic powders; and the influence of plastic anisotropy on the hydrogen embrittlement of titanium under multiaxial states of stress.
