Determination of the Entire Existence Composition Range of CrMnFeCoNi High-Entropy Alloys Using Sintered Diffusion Multiple Method.

ABSTRACT: The sintered diffusion multiple (SDM) method, which has been developed in our research group, has been applied to determine the entire composition range of the CrMnFeCoNi high-entropy alloy stereoscopically and continuously over nearly the entire range. The samples were prepared by sintering mixed elemental powders and were annealed at 970 °C or 800 °C. Several hundreds of thousands of points were analyzed at random within the samples for chemical compositions using electron probe microanalysis. With the assumption that ideally, only chemical compositions of existing phases at the temperature of annealing are obtained, the compositional data thus obtained were analyzed to estimate the phase boundaries of the high-entropy phase, including the Cantor alloy composition, assuming local equilib
