摘要：

The non-metallic inclusions found distributed throughout C-Mn and High Strength Low Alloy (HSLA) steel weld metals are the result of deoxidation and/or desulphurization reactions taking place within the weld pool. It is now widely recognized that these inclusions, typically 0. 2-2. 0 mu m in diameter, play an important part in microstructural development in ferritic weld metal. Although there have been various reports of compositional variations in these inclusions there has been no report of detailed microanalysis of inclusions in shielded metal arc weld metal. This letter reports some of the findings of an investigation into inclusion composition and morphology in shielded metal arc, C-Mn steel weldments.
