Abstract

In order to get higher strength and toughness of steel weld metal, effects of microalloying elements on the strength and toughness of 0.01%C cast steel specimens in stead of steel weld metal have been investigated. The microalloying elemtns used were Al, Ti, Zr, Nb and V.
The findings of the experiment are as follows;
1. Aluminum addition up to 0.076% decreases the transition temperature of as-cast specimen, but does not increase the strength.
2. Niobium addition of 0.02% increases the strength without sever reduction of toughness.
3. Titanium, zirconium or vanadium additions increase the strength of as-cast specimens, but reduce the toughness severly.
