摘要：

The effect of annealing-temperature on the microstructure and properties of the low-melting point high-entropy alloy Fe35Ni30Cr20Al10Nb5 (molar ratio) were systematically investigated. The results show that with the increasing annealing-temperature, the volume fraction of Fe-Cr-rich fcc phase gradually decreases, while the volume fraction of Laves phase and B2-NiAl phase gradually increases for the as-cast alloy. The quasi-static compression test results show that the as-cast alloy has good compressive plastic deformation ability, and the yield strength of the alloy increases and then decreases as the annealing-temperature increases. The decrease in compression yield strength with the rising annealing-temperature is mainly attributed to the decomposition of the fcc phase at higher temperatures. The electrochemical test results show that the corrosion resistance of the alloy increases monotonically with the annealing-temperature, and the free-corrosion potential of the alloy annealed at 900oC is -72.02 mV. © 2024 Chinese Journal of Materials Research.
