Dendrite fragmentation induced by massive-like δ–γ transformation in Fe–C alloys

Dendrite fragmentation induced by massive-like δ–γ transformation in Fe–C alloys

Transitioning from columnar to equiaxed grains is paramount for desired microstructures during steel casting. Here, the authors report a new fragmentation mechanism based on a phase transition at grain boundaries that can contribute to equiaxed grains.
