CX-270185: CFA-16-10285: Tribological Damage Mechanisms from Experiments and Validated Simulations of Alloy 800H and Inconel 617 in a Simulated HTGR/VHTR Helium Environment – Purdue University

Purdue University proposes to perform a series of tribological experiments on Alloy 800H and Inconel 617 in a simulated He environment with controlled concentrations of gaseous species follow by microstructure characterization using electron microscopy, spectroscopy, and atom probe tomography, and the development of validated macroscopic models informed by properties/mechanisms at the atomistic level.
