Abstract
The shape of austenite grains in low-alloy steel submerged-arc weld deposits has been examined; it is found that the grain morphology can be approximated as a honeycomb of hexagonal prisms with their “c” axes aligned along the major heat-flow direction. Methods of determining the grain size from simple stereological measurements are also discussed. An increase in the oxygen content has not been found to reduce the austenite grain size of as-deposited welds.
