Experimental investigations on the quinary interdiffusivities in diffusion couples of NiAlCoCr alloy/CoCrFeNi high-entropy alloys
Source abstract
Abstract
The diffusion couples composed of Ni–Al–Co–Cr alloys and low-entropy (pure Ni, and NiCo, NiCr, and NiCoCr)/medium-entropy (CoCrNi)/high-entropy (CoCrFeNi) alloys were fabricated, and subjected to annealing at 1473 K for 72 h. Their composition profiles were measured by using the electron microprobe analysis technique. By combining the measured concentration profiles and the free-accessible High-throughput Determination of Interdiffusion Coefficients (HitDIC) software, the composition-dependent interdiffusion coefficients in the diffusion couples along the entire diffusion paths were determined in a high-throughput manner. The general relation, D ˜ C r C r N i > D ˜ F e F e N i > D ˜ C o C o N i , exists in most diffusion couples. A comprehensive comparison of the presently interdiffusion coefficients of elements in presently low-, medium- and high-entropy alloys and the available data in the literatures were conducted.
