Small-scale mechanical behavior of a eutectic high entropy alloy [PDF]

Scientific Reports, 2020
AbstractEutectic high entropy alloys, with lamellar arrangement of solid solution phases, represent a new paradigm for simultaneously achieving high strength and ductility, thereby circumventing this well-known trade-off in conventional alloys. However, dynamic strengthening mechanisms and phase-boundary interactions during external loading remain ...

Phase-Specific Damage Tolerance of a Eutectic High Entropy Alloy

Entropy, 2023
Phase-specific damage tolerance was investigated for the AlCoCrFeNi2.1 high entropy alloy with a lamellar microstructure of L12 and B2 phases. A microcantilever bending technique was utilized with notches milled in each of the two phases as well as at the phase boundary.
