Hydrogen embrittlement can occur in steels with metastable phases, due to activation of the hydrogen-enhanced decohesion mechanism upon transformation. Meanwhile, recent investigations suggest that alloys undergoing e-martensite transformation may ex

Hydrogen uptake causes hydride formation, lattice strains and other crystallographic changes in Ti6Al4V. To monitor these changes and understand them better, we developed an in situ hydrogen-charging setup for transmission X-ray diffraction, and empl

The high-entropy alloy (HEA) concept was based on the idea that high mixing entropy can promote formation of stable single-phase microstructures. During the past 15 years, various alloy systems have been explored to identify HEA systems with improved
