Abstract
We analysed inclusions formed in low-carbon steel weld metals using focused ion beam transmission electron microscopy. The Al/O mass ratios were varied from 0.28 to 1.63 mass%, and the effects of the Al/O ratio on the inclusions and on the phase-transformation (PT) behaviour were investigated. Our analysis revealed that boron was distributed in the amorphous phase in the inclusions and this strongly affected the PT behaviour of grain-boundary ferrite and acicular ferrite.
