Abstract

It has been established that in weld metal of microalloyed steel the ferritic structure dominates, occurring in different morphologic forms. The most dominating form in the weld metal depends on a significant number of factors. In this paper acicular ferrite as a morphologic form is described that occurs in weld metal of microalloyed steel and contributes to weld metal strength and toughness.

Keywords: acicular ferrite, weld metal, microstructure, low carbon steel, inclusions
