Abstract

The effect of niobium microaddition in C-Mn steel on microstructure, tensile properties, ductile-brittle transition temperature, and weldability have been investigated. Niobium microaddition adversely affects the transition temperature and toughness of the heat-affected zone, counteracting its favorable effects of refined grain size and low inclusion and pearlite content.
