Advanced Processing and Properties of High Performance Alloys

Abstract

Progress is reviewed for a research program whose purpose is 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. While some of the research is specific to certain alloy systems, much of the program constitutes fundamental study of the deformation and fracture of engineering alloys containing processing-induced defects. Progress for the period January 1, 1988, to December 31,1988, is reviewed for the following projects within the program. the influenced of porosity on low cycle fatigue, the mechanism of strain-induced void/pore linking during ductile fracture, and the processing and properties of CU-NB micro-composites. Keywords: Physical metallurgy; Physical properties; Low cycle fatigue; Metal fatigue; Niobium; Copper; Alloys.
