Evaluation of hydrogen embrittlement in ODS-Cu, Cu–Cr–Zr, and Cu–Cr alloys using slow strain rate technique test

Nuclear Materials and Energy
Precipitation-hardened Cu–Cr–Zr alloy is proposed as a heat sink material for various components of the ITER owing to its high strength, high conductivity, and superior resistance against neutron irradiation. Oxide-dispersion-strengthened copper (ODS-Cu)

Preventing hydrogen embrittlement in stainless steel by means of compressive stress induced by cavitation peening

The Journal of Engineering, 2015
In this paper, it has been demonstrated that compressive residual stress induced by cavitation peening which is one of the mechanical surface modification techniques can reduce invasion of the surface of austenitic stainless steel by hydrogen. Cavitation

Modeling current density and SoC distribution of all-solid-state lithium-ion batteries

Electrochemistry Communications
Researchers have conducted in-depth investigations into lithium-ion battery models. However, a notable limitation of existing models lies in the assumption of infinitely conductive current collectors, which compromises simulation accuracy.
