Symposium SF08—Far From Equilibrium Microstructure Evolution in Metals

This symposium will explore the scientific frontiers of driven and non-equilibrium microstructure evolution in metals. The microstructure of metallic materials evolves continuously during processing and in service. This evolution is often described as a gradual approach to thermodynamic equilibrium, as solutes partition, defects anneal, and grains grow. However, under intense, external driving forces, metal microstructures may evolve in different and often unanticipated ways: high strain rate compression forms metastable phases, irradiation causes grain refinement, and continuous cyclic loading generates complex defect aggregates. Such driven microstructure evolution leads to early failure, in some cases. In others, it gives rise to steady-state, far-from-equilibrium microstructures with enhanced performance. Similarly, far-from-equilibrium processing methods open opportunities for the synthesis of unconventional, hitherto unexplored metal microstructures.

This symposium will provide a forum for presenting cutting-edge research on far-from-equilibrium microstructure evolution in metallic materials during processing and under exposure to external drivers.

• Microstructure evolution across length scales—from atoms, to defects, to grains, to grain aggregates—and across time scales: from atomic vibrations to long-term aging
• Diverse external driving forces, including deformation at all strain rates, irradiation, rapid heating/cooling, and exposure to electromagnetic fields
• Far-from-equilibrium microstructure processing, such as laser rapid solidification, physical vapor co-deposition, and severe plastic deformation
• Investigation of microstructure evolution through advanced experiments, simulations, and theory
• All classes of metallic materials: crystalline and amorphous, single- and multi-phase, conventional and novel
• Technological implications of far-from-equilibrium microstructure evolution
