摘要：
As part of an investigation into the microstructure and properties of low carbon microalloyed steel weld metal, the influence of changes in the optically resolvable microstructure on Charpy impact transition temperatures were examined. An analysis of the experimental data was carried out, based on the premise that minor phases were the primary sites for brittle crack initiation, and that successful propagation or otherwise of such cracks was a function of the surrounding gross microstructure. The resulting correlation between microstructure and toughness provided a means of rationalizing the influence of a range of compositional and other variables on toughness, through their effects on the microstructure.
