Abstract
By combining solid-state diffusion couple experiments with a numerical inverse method, the interdiffusion coefficients in NiAlCoCr/CoCrFeMn0.2Ni and NiAlCoCr/CoCrCu0.2FeNi diffusion couples were determined at 1,273–1,373 K, and their reliability was verified. The main interdiffusion coefficients on the NiAlCoCr alloy side were greater than those on the high-entropy alloy side at 1,273–1,373 K. The main interdiffusion coefficients followed the trend:
