Aspect ratios and morphology of acicular ferrite in C-Mn-Ni weld metals
Aspect ratios and morphology of acicular ferrite in C-Mn-Ni weld metals
The aspect ratio and morphology of acicular ferrite formed in C-Mn-Ni weld metals and the effect of nickel and oxygen contents have been investigated. The experimental results revealed that nickel has a strong effect on the acicularity of acicular ferrite in C-Mn-Ni weld metals. High nickel contents resulted in sharper acicularferrite laths with a larger aspect ratio. It is considered that the two dominant mechanisms are the role of nickel in changing the balance of incoherent/coherent growth ledges, and the transformation temperatures at which this growth takes place. Reducing the oxygen content in the weld metals was also found to increase the aspect ratio.

Abstract
The aspect ratio and morphology of acicular ferrite formed in C-Mn-Ni weld metals and the effect of nickel and oxygen contents have been investigated. The experimental results revealed that nickel has a strong effect on the acicularity of acicular ferrite in C-Mn-Ni weld metals. High nickel contents resulted in sharper acicularferrite laths with a larger aspect ratio. It is considered that the two dominant mechanisms are the role of nickel in changing the balance of incoherent/coherent growth ledges, and the transformation temperatures at which this growth takes place. Reducing the oxygen content in the weld metals was also found to increase the aspect ratio.
