A generalized mechanical blocking criterion for the columnar-to-equiaxed transition during additive manufacturing

We present a fully general model for the columnar-to-equiaxed transition (CET) that extends the classical mechanical blocking models to completely arbitrary nucleation-undercooling distributions and dendrite growth laws. The general approach is compared to the classical models for a recently reporte...
