Creep in CoCrFeMnNi a compositionally complex high-entropy alloy
Original language description
Understanding creep in concentrated solid solution is important for at least two reasons: (i) controversies still exist concerning the classification of solid solutions into Class I and Class II creep behaviors [1] and (ii) certain concentrated alloys often represent key constituents of high temperature engineering materials. In the present work, a compositionally complex quinary alloy, CoCrFeMnNi, which crystallizes as single FCC phase and exhibits apparent thermodynamic stability in a wide temperaturerange [2], has been investigated as a representative model system. Arc-melted and drop-cast ingots of CoCrFeMnNi with the equiatomic composition were thermo-mechanically treated prior to creep in order to obtain microstructures with grain sizes in the range 20-50 ?m. Tensile and compression tests were performed at 1073 K in range of applied stresses. Microstructures after deformation were investigated using advanced SEM and TEM techniques. Results obtained on specimens crept at 1073 K s
