Abstract: There is compelling evidence for the critical role of twin boundaries in imparting the extraordinary combination of strength and ductility to nanotwinned metals. This paper presents a study of the thermal expansion of ...

Abstract: Grain boundary (GB) plays a crucial role in the mechanical properties and irradiation resistance of nuclear materials. It is thus essential to understand and predict the defect behaviors near GBs. Here, we present a framework ...

Abstract: Hydrogen embrittlement poses a significant challenge to hydrogen transportation and storage in advancing the hydrogen economy. Despite extensive research, uncertainty regarding how hydrogen affects dislocation nucleation, ...
