摘要

•High entropy alloy films with single phase B2 AlCoCrFeNi fabricated from multilayers.•Self-propagating combustion using Al/Ni multilayers is used as an ultrafast heat source.•Fast scanning calorimetry reveals that the phase formation sequence depends on heating rate.•High heating rates avoid long-range diffusion and intermediate phases.
