Analyzing the ‘non-equilibrium state’ of grain boundaries in additively manufactured high-entropy CoCrFeMnNi alloy using tracer diffusion measurements

Additively manufactured (AM) metallic materials contain typically numerous grown-in defects which limit durability and mechanical properties of workpieces. However, the existence and impact of non-equilibrium vacancies and dislocations and especially the state of grain boundaries in AM materials rem...
