Abstract

Abstract: This study investigates the effects of solution and aging treatments on the microstructure and mechanical properties of as-deposited Al₁₇Cr₁₀Fe₃₆Ni₃₅Mo₂ FCC/B2 dual-phase high-entropy alloy. The B2 phase within the dendrites dissolves, and the lamellar structure disappears, resulting in a dual-phase microstructure of B2 dendrites and interdendritic FCC phases after heat treatment. The tensile strength of the solution and aging alloy increased from 1266 MPa to 1441 MPa. The enhancement in strength is attributed to the precipitation of nanoscale L1₂ and spherical BCC phases within the FCC and B2 matrices. This work provides valuable insights into precipitation strengthening strategies for additive-manufactured dual-phase high-entropy alloys.
