Abstract: Abstract Equimolar CoCrFeMnNi high-entropy alloy (HEA) could be effectively strengthened by grain refinement process. However, the dislocations, grain boundaries and twins determined by the grain refinement process worked as hydrogen diffusion paths and trapping sites… read more here.

DOI: 10.1016/j.scriptamat.2020.05.060
Abstract: Abstract Tracer-diffusion of constituting elements in single-crystalline CoCrFeNi and CoCrFeMnNi is measured from 923 K to 1373 K. In CoCrFeMnNi, low-temperature deviations from otherwise linear Arrhenius-type dependencies are seen for all elements excluding Mn. The kinks are… read more here.
