Purpose: The study aims to investigate the effects of thermomechanical treatment, including tempering and hot–rolling, on the microstructure and mechanical properties of ferrite–martensite dual phase steel. Design/methodology/approach: The initial steel billet was a hypoeutectoid steel, which was annealed at 1000ºC, then hot–rolled at 920ºC, followed by austenitisation at various temperatures (730, 770, 800, and 830ºC), and finally quenched to obtain ferrite–martensite dual phase steel. X-ray diffractometer and optical microscopy investigated the microstructure and grain size of the dual-phase steel. Mechanical properties such as hardness, elongation, and tensile strength were also examined. Findings: The grain size decreased with increasing elongation percentage and remained constant after an elongation of 30%. The martensite/ferrite phase ratio increased with higher tempering temperatures. The hardness, elongation, and tensile strength reached a maximum when the tempering temperature was 800ºC. Research limitations/implications: Future studies could consider the effect of hot–rolling temperature or cold-rolling. Practical implications: The study proposes a straightforward and efficient thermomechanical treatment process to transform hypereutectoid steel into ferrite-martensite dual-phase dual- phase steel with improved mechanical properties. Originality/value: The study reveals the contributions of grain size and the martensite/ferrite ratio to the mechanical properties of ferrite–martensite dual steel through thermomechanical treatment.
