Mechanism of grain refinement in ferritic stainless steel welds: between dendrite fragmentation, grain detachment and heterogeneous nucleation

The morphology of the grain structure in fusion welds is generally columnar and elongated. This structure is highly anisotropic and makes weld metal susceptible to centerline hot cracking and poor notch impact toughness particularly in welds that are prone to brittle fracture such as the ferritic s...
