Correlation of Inclusion Size and Chemistry with Weld Metal Composition andMicrostructure Arc Weldments of High Strength Steels

摘要

Non-metallic inclusions are crucial to the development of acicular ferrite, thedesired microstructure for optimal strength and toughness in weld metal. This study focused on obtaining correlation between the size and chemistry of inclusions and weld metal properties, especially the amount of acicular ferrite,
