|On-Site Speaker (Planned)
In this talk, which we dedicate to Professor Murty, we will show how alloy complexity leads to greater tolerance to irradiation damage but the relationship is multifaceted and does not depend simply on the number of elements in the alloy. Specifically, the evolution of damage in a series of Ni-containing single-phase solid solution alloys under electron and ion irradiation will be presented. The dynamics of the damage evolution as well as the mobility of the damage is captured through the use of in-situ irradiation and characterization in a transmission electron microscope. In addition to the defects produced it will be shown that the local compositional state of the alloys is impacted by the irradiations. These effects will be explained in terms of the modifications of the energy dissipation processes and defect formation and migration energies due to the compositional complexity of the alloys.
||Planned: Stand-alone book in which only your symposium’s papers would appear (indicate title in comments section below)
