Abstract
Phase-selective recrystallization process has been confirmed as an effective way to improve the ductility of dual-phase alloys. Here, the tensile property of a low-cost dual-phase Fe37Ni36Cr10Al17 alloy was significantly improved via phase-selective recrystallization and aging. The equiaxed microstructure was obtained after phase-selective recrystallization and the tensile elongation significantly increases compared with as-cast alloy. Furthermore, the tensile strength increased to 1369.0 MPa and elongation increased to 23.0% by aging. The comprehensive property shows great potential applications for industrial prospects.
