Four Dimensional (4D) X-ray Microtomography of Stress-Corrosion Cracking in High Performance Metallic Materials

Abstract

Funds are provided to study cracking in metallic materials.Technical POC: Dr. William M. Mullins, william.m.mullins@navy.milThis project addresses directly the PE 0601153N objectives for furthering basic research efforts including scientific study and experimentation directed toward increasing knowledge and understanding in national security related aspects of physical, engineering, environmental, and life sciences.Proposal Abstract:The stress corrosion cracking and of aluminum alloys is very important in structural applications. State-of-art in situ x-ray tomography techniques for microstructural characterization are ideal for providing a fundamental quantitative understanding of microscopic mechanisms of damage evolution over time. The insight provided by these techniques will result in unprecedented advances in our understanding of the physics of combined stress and environmental effects on plasticity and mechanisms for degradation and damage evolution. Specifically, the following important issues need to be addressed:
