Synthesis of ultrafine dual-phase structure in CrFeCoNiAl0.6 high entropy alloy via solid-state phase transformation during sub-rapid solidification
文献摘要：
High entropy alloys(HEAs)with superb mechanical properties have been traditionally produced by solid-ification and subsequent heat treatment.In this paper,we demonstrate a new route via one-step pro-cess using sub-rapid cooling.Under proper cooling rates,the CrFeCoNiAl0.6 HEA could form ultrafine FCC+BCC dual-phase structure.By varying cooling rate,we can control the fraction of the BCC phase and refinement of FCC microstructures that have tunable mechanical properties in yield strength and hardness ranging from～580 to～1460 MPa and～260 to～550 Hv.We show that the structure-property-processing relation originates from the sideplate microstructures formed during fast cooling that have specific crystallographic orientation relationship between the FCC and BCC phases and chemical segrega-tion.This work provides a new setting for better understanding of the solid-state phase transformation in HEAs under sub-rapid solidification conditions as well as a novel method for development of high-performance HEAs.
