Thermal Stability of NI(AL)/NI3AL Nanolayered Materials

Abstract

The purpose of this ASSERT-sponsored research is to study the morphological stability of Ni(Al)/Ni3Al nanoscale layered materials, as a function of interfacial orientational relationship, columnar grain dimensions, bilayer thickness, applied stress, and temperature. This final report describes our efforts over the course of the project to study the morphological stability of Ni(Al)/Ni3Al multiplayer thin films that are heated to elevated temperature for prolonged periods. This area, when coupled with the objective of the parent project to optimize plastic strength in such materials, represent two critical design areas for nanoscale materials. This final report describes our efforts to both model the thermal stability of Ni(Al)/Ni3Al nanoscale layered materials and to conduct experiments to determine the temperature and time scales over which the layered morphology in such materials may break down.
