Phase field modeling of dendritic coarsening during isothermal

Dendritic coarsening in Al-2mol%Si alloy during isothermal solidification at 880K was investigated by phase field modeling.Three coarsening mechanisms operate in the alloy: (a) melting of Metal Desk Lamp (1/CN) small dendrite arms; (b) coalescence of dendrites near the tips leading to the entrapment of liquid droplets; (c) smoothing of dendrites.De
