The load redistribution between and within phases in eutectic high entropy alloy AlCoCrFeNi2.1 was measured using in-situ neutron diffraction during tensile deformation at 973 K. partitioning is reversed compared to lower temperatures, with L12 becoming the stronger phase. evolution of orientation-specific stresses strains phase suggests that cube slip dominates response. low strength, internal transfer ideally plastic response B2 indicate a change mechanism temperatures.
