In 1959 the Journal of Nuclear Materials (JNM) was founded and is now celebrating its
Diamond Anniversary year. The present paper is part of a series in which single JNM …

Helium (He) bubbles are typical radiation defects in structural materials in nuclear reactors
after high dose energetic particle irradiation. In the past decades, extensive studies have …

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 …

A body-centered cubic W-based refractory high entropy alloy with outstanding radiation
resistance has been developed. The alloy was grown as thin films showing a bimodal grain …

How displacement damage defects generate and evolve in materials irradiated by energetic
particles is a perennial topic in the field of nuclear materials. Here we experimentally reveal …

Tungsten plays a significant role in the nuclear industry, in which defects are generated
upon exposure to irradiation. Irradiation-induced defects, such as dislocation loops and …

In-situ TEM observation and molecular dynamics simulation were used to investigate the
evolution of irradiation-induced dislocation loops and their interactions with the pre-existing …

In-situ irradiations with 30 keV He+ were performed on tungsten in an investigation of the
influences of irradiation temperature and fluence, pre-existing dislocation and sample …

Tungsten has been chosen as the plasma-facing wall material in fusion reactors, due to its
high density and melting point. The wall material will not only be sputtered at the surface, but …

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