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 is reviewed for the following projects within the program: modeling the effects of pores or voids on fracture, the processing and properties of Cu-Nb alloy, and a new age-hardenable beta titanium system.
