In the quest of new materials that can withstand severe irradiation and mechanical extremes
for advanced applications (eg. fission & fusion reactors, space applications, etc.), design …

Ductile-to-brittle transition (DBT) is a well-known phenomenon in body-centered-cubic
(BCC) metals, intermetallics and semiconductor materials. A quantitative prediction of the …

Calculations of dislocation-defect interactions are essential to model metallic strength, but
the required system sizes are at or beyond ab initio limits. Current estimates thus have …

In this work, using in-situ uniaxial tensile and compressive testing, microscopy, and
theoretical analysis, we study the mechanism underlying the ultrahigh irradiation hardening …

The present work reports an abnormal negative strain-rate sensitivity (SRS) in a room-
temperature quenching and partitioning (RT-Q&P) steel. The mechanisms responsible for …

Atomic-scale defects generated in materials under both equilibrium and irradiation
conditions can significantly impact their physical and mechanical properties. Unraveling the …

Tungsten is a promising candidate material for plasma-facing armour components in future
fusion reactors. A key concern is irradiation-induced degradation of its normally excellent …

High-Entropy Alloys (HEAs) are proposed as materials for a variety of extreme
environments, including both fission and fusion radiation applications. To withstand these …

In materials exposed to neutron irradiation, helium atoms produced by transmutation
reactions are prevalent and play a significant role in the evolution of dislocation loops …

The evolution and dynamic behaviors of dislocation loops in tungsten (W) under 30 keV H
2+ irradiation have been studied through in-situ TEM observation. The study covered a dose …
