Varying the eutectic composition of Co–Cr–Fe–Ni-Hf high-entropy system using a modified simple mixture method

Different eutectic compositions were successfully obtained for Co–Cr–Fe–Ni-Hf high-entropy system using a proposed modified simple mixture method when treating equal-atomic CoCrFeNi and CoaCrbFecNidHfe as two independent parts. Varying eutectic composition opens an avenue to tune microstructures and, in turn, improve mechanical properties of eutectic high-entropy alloys.
