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

Tracer diffusion of Co, Cr, Fe and Ni is measured at 1373 K in Co20Cr20Fe20Mn20Ni20, Co10Cr10Fe10Mn10Ni60 and Co2Cr2Fe2Mn2Ni92 alloys. Diffusion retardation in the high-entropy Co20Cr20Fe20Mn20Ni20 alloy is most prominent in comparison to the Co2Cr2F

High entropy alloys are multicomponent alloys, which consist of five or more elements in equiatomic or nearly equiatomic concentrations. These materials are hypothesized to show significantly decreased self-diffusivities. For the first time, diffusio

Tracer diffusion of all constituting elements is studied at various temperatures in a series of (CoCrFeMn) 100 − x Nix alloys with compositions ranging from pure Ni to the equiatomic CoCrFeMnNi high-entropy alloy. At a given homologous temperature,

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
