Deformation Mechanisms in Multilayered Materials for High Temperature Application

摘要

The aim of the proposed research is to understand how nanoscale laminates with optimal strength, ductility, and elevated temperature stability can be engineered through the selection of component chemistry, component layer thickness, and interfacial and grain boundary structure. The first effort is to develop computational tools to model the deformation and fracture processes in nanoscale laminates based on a well-known intermetallic system. The second effort is to apply the computational tools to at least one additional laminate system.
