Clarification on development of skeletal and lathy ferrite morphologies in stainless steel welds

Abstract

Inoue and co-workers have quoted the present authors as reporting that lacy (or lathy) ferrite in austenitic stainless steel welds forms only during single phase ferrite solidification (F). It was actually reported that both lathy and skeletal ferrite morphologies had been observed in single phase ferrite solidified welds. However, it was also reported that these two ferrite morphologies were observed in F/A (primary ferrite with secondary solidification as austenite) solidified welds. The aim of this letter is to clarify that both ferrite morphologies were observed in both F and F/A solidification modes.
