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 a certain ally systems, many aspects of the program constitute fundamental studies of the deformation and fracture of engineering alloys containing processing - induced defects. Progress for the period May 1, 1986 to January 31, 1987 is reviewed for te following projects within program: (1)the mechanism of void/pore linking in ductile fracture, (2)the influence of porosity on low cycle fatigue, (3) the deformation of rapidly solidified Ti alloys at elevated temperatures, (4) strain-path effects on fracture, and (5)hot isostatic pressing of metallic powders. Keywords: Processing, Fracture mechanisms, Void/Pore linking, low cycle fatigue, rapidly solidified alloys, Ti alloys, hot isostatic pressing (HIP), strain-path effects.
