Advanced Processing and Properties of High Performance Alloys

Abstract

Progress is reviewed for a research program whose purpose was to establish a broad-based understanding of the application and consequences of advanced processing techniques, especially as they influence the strength and fracture resistance of high performance structural alloys. The research areas are as follows: (1) the mechanism of strain-induced void/pore linking during ductile fracture, (2) the influence of porosity of low cycle fatigue mechanics, (3) processing and properties of copper/niobium alloys, (4) the deformation of rapidly solidified titanium alloys at elevated temperatures, (5) strain-path effects on fracture, and (6) a new age-hardenable beta titanium alloy.
