Abstract

A novel chemically heterogenous high carbon bainitic steel was developed via controlling initial partitioning of austenite stabilized element (Mn) and strong carbide-forming element (V), fast heating to austenization and low-temperature austempering treatments. The newly developed bainitic steel with exciting high yield strength and ductility is expected to break the dilemma of strength-ductility trade-off. The increased yield strength is primarily originated from precipitation strengthened retained austenite and refined bainitic matrix, while the good ductility benefits from Mn-induced chemical heterogeneity.
