Rapid precipitation of L12 phase in Al0.5CoCrFeNi high-entropy alloy under electropulsing
A new strategy for the rapid precipitation (1.8 s) of L12 nanoprecipitates in Al0.5CoCrFeNi high-entropy alloys by electropulsing treatment (EPT) has recently been discovered. The coherent L12 phase was introduced under high temperatures by EPT, and this result broke the previous understanding that...

| description | A new strategy for the rapid precipitation (1.8 s) of L12 nanoprecipitates in Al0.5CoCrFeNi high-entropy alloys by electropulsing treatment (EPT) has recently been discovered. The coherent L12 phase was introduced under high temperatures by EPT, and this result broke the previous understanding that it needs to be aged for a long time at low temperatures. The formation of the L12 precipitates was mainly attributed to the combination of thermal and athermal effects during EPT. This work provides insights into the rapid regulation of multiphase (FCC + B2 + L12) and dislocation combinations in high-entropy alloys to optimize strength and ductility. |
