PREDICTION OF FORMED PHASES IN TWO HIGH ENTROPY SYSTEMS

Popis výsledku v původním jazyce

Work deals with phase formation of eight high entropy alloys of FeCuxCr1-xMnNi type and of three alloys of FexCuCrMnNi system with high entropy effect. Predicted compositions of phases using Ni and Cr equivalents and by use of valence electron concentration are compared with real finding of presented phases in all aforesaid systems. Types of phases were detected by hard X-ray synchrotron micro-diffraction. With increasing Cr content in FeCuxCr1-xMnNi system double FCC phases changed into double FCC with BCC phases under simultaneously increase of yield stress. In FexCuCrMnNi system with atypical higher Fe content double FCC phases were detected with their different volume fractions. With increasing Fe content as a BCC stabilizer a rise of yield stress was detected. In both investigated systems, predicted results of formed phases partially differed from founded phases using synchrotron.
