Accelerated development of high performance structural alloys is important for multiple applications including utility-scale fossil and nuclear energy systems as well as advanced aerospace systems. This presentation will summarize recent fundamental and applied research results that are relevant for accelerated design and discovery of advanced structural materials. Examples of fundamental questions being explored using ion beam bombardment as a convenient diagnostic probe include: how quickly can nanoscale volumes respond to rapid temperature quenches and re-establish thermal equilibrium phases; relevance of ion beam dynamic ballistic dissolution and radiation enhanced renucleation and growth processes for understanding precipitation kinetics; and utilization of implanted inert marker atoms to examine vacancy-driven thermal creep phenomena. Recent progress using directed energy deposition to fabricate oxide dispersion strengthened FeCrAl will be summarized, along with a comparison of conventional and field assisting sintering technologies to fabricate a novel creep-resistant high conductivity Cu alloy designed by computational thermodynamics.
