Effect of feeding Ca–Mg–RE–Zr composite cored wire during refining of liquid steel on weldability of ultrahigh strength wear resistant steels
Source abstract
Abstract
The weldability and mechanical properties of an ultrahigh strength wear resistant steel were substantially improved by the addition of a small amount of Ca–Mg–RE–Zr composite (1·5 kg t−1) to the molten steel during the refining stage. Based on optical and electron microscopy examinations, the observed improvements were attributed to the enhanced pining effect of inclusions on the original austenite grain boundaries within the coarse grained heat affected zone, as well as the inclusion induced acicular ferrite formation within the fine grained heat affected zone.
