Advanced Processing and Properties of High Performance Alloys.

Abstract

Progress is reviewed for a research whose purpose is to provide a fundamental understanding of the applications and consequences of selected advanced processing techniques to high performance alloys. The research ranges from modelling studies of the fracture of alloys containing porosity to the high temperature deformation of rapidly solidified, dispersion-strengthened titanium alloys. Many aspects of the research are also fundamental studies of fracture utilizing engineering alloys. Many aspects of the research are also fundamental studies of fracture utilizing engineering alloys containing processing-induced defects. Progresss for the period October 1, 1984 to September 30, 1985 is reviewed for the following studies comprising this research program: (1) the influence of void/pore distributions on ductile fracture; (2) the effect of porosity on low cycle fatigue; (3) hot isostatic pressing of metallic powders; (4) deformation of rapidly solidified Ti alloys at elevated temperatures; and (5) the combined effect of stress state and grain size on hydride-induced hydrogen embrittlement. Keywords: Powder metallurgy. (Author)
