Abstract
Microstructural development during the Q&P process of a 0.3C-1.6Si-3.5Mn (wt. %) steel with an inhomogeneous chemical composition is studied by applying local EPMA and optical microscopy techniques. During the initial Q&P quenching, the fraction of formed martensite is higher in the Mn/C-poor regions than Mn/C-rich regions. Due to the lower fraction of M1, austenite in the Mn/C/Si-rich regions has lower probability to receive sufficient carbon than austenite in the Mn/C/Si-poor regions. Consequently, during the final quench higher fraction of M2 is formed in the Mn/C/Si-rich than in the Mn/C/Si-poor regions.
