In the current research, a complex microstructure and crystallographic data were developed through quenching partitioning (Q&P) process to improve tensile properties of commercial pearlitic carbon-silicon steel. Two-stage Q&P process, including full austenitization, at 220 °C, followed by two different temperatures, was applied as-received specimen generate composed tempered martensite, bainite...

This study consists of the experimental and numerical analysis phase transformations 5Cr-0.5Mo.0.1C steel after heat treatment. The microstructure as-received comprised ferrite bainite, which is in agreement with microconstituents predicted by Calphad-calculated TTT diagram. Calphad-based precipitation calculations show that cooling stage normalizing treatment did not cause carbide formation. I...
