Solid-state phase transformation is usually associated with excellent mechanical properties in steel materials. A deep understanding of the formation and evolution of phase structure is essential to tailor their service performance. As a powerful tool for capturing the evolution of complex microstructures, phase-field simulation quantitatively calculates the phase structures evolution without explicit assumptions about transient microstructures. With the development of advanced numerical technology and computing ability, phase-field methods have been successfully applied to solid-state phase transformation in steels and greatly support the research and development of advanced steel materials. The phase-field simulations of solid-phase transformation in steels were summarized, and the future development was proposed.
