dc.description.abstractSubmerged arc weldments of HY-100 steel prepared under standard conditions with five commercially available fluxes were analyzed to discern a basis for the variation in mechanical properties associated with different flux use. The variations in flux chemistry resulted in alloyed weldments with diverse weld metal mechanical properties as evident by Charpy impact, tensile, dynamic tear, and microhardness tests. The microstructures and macrostructures were examined using optical and electron microscopy in order to determine the basis for the variations in strength and toughness. Scanning electron microscope and energy dispersive x-ray experiments were performed to determine the size, type, distribution and volume fraction of the non-metallic inclusions in the weld metal. Inclusion characterization revealed that the role of the flux in alloying had a more significant effect on the strength and toughness than did the presence of specific inclusions.en_US
