Microstructures formation and phase transformations around the interface of welds between dissimilar steels

The goal of this study is to understand the complex microstructures which form at the interface between a low-alloy steel and a stainless steel during welding and subsequent heat-treatment at 610 ∘C. A dual approach with both experimental measurements and thermodynamic and kinetic modeling has been chosen for both solidification and solid-state phase transformations. A very good agreement has been obtained for the carbon profile across the interface and the nature of phases which form.
