Development of microalloyed steels and its design aspects Part I : Medium and low carbon micro-alloyed forging steels

Abstract

The development in microalloyed forging steels (MAFS) has undergone a revolution during last four decades. The extent of carbon, manganese, silicon and one or more microalloying element significantly affects the microstructure of the transformation product and in turn its mechanical properties strength and toughness. The processing conditions too play an important role in determining the mechanical properties of the final component. Microalloyed forging steels have found potential application in critical auto components leading to hyper productivity and overall cost reduction.
