Irradiation-Driven Recrystallization in Fusion-Grade Tungsten: A Mesoscale, Microstructure-Aware Model
Jinxin Yu, Sicong He, Giacomo Po +3
Tungsten (W) is the leading candidate material for plasma-facing components in fusion reactors, yet its upper operational temperature is limited by premature grain growth and recry…
Parameter-free prediction of irradiation defect structures in tungsten at room temperature using stochastic cluster dynamics
Sicong He, Brandon Schwendeman, George Tynan +1
The foundations of irradiation damage theory were laid in the 1950s and 60s within the framework of chemical reaction kinetics. While helpful to analyze qualitative aspects of irra…
Grain boundary metastability controls irradiation resistance in nanocrystalline metals
Osman El-Atwani, Annie K. Barnett, Enrique Martinez +13
Grain boundaries (GBs) in polycrystalline materials are powerful sinks for irradiation defects. While standard theories assume that the sink efficiency of a grain boundary is defin…
Thermal super-jogs control high-temperature strength in Nb-Mo-Ta-W alloys
Sicong He, Xinran Zhou, Dan Mordehai +1
Refractory multi-element alloys (RMEA) with body-centered cubic (bcc) structure have been the object of much research over the last decade due to their high potential as candidate…
