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 small dendrite arms; (b) coalescence of dendrites near the tips leading to the entrapment of liquid droplets; (c) smoothing of dendrites. Dendrite melting is found to be dominant in the stage of den... https://www.roneverhart.com/HP-15-EF1005DS-15-6-Laptop-HD-LED-BV-1366-x-768-AMD-ATHLON-Silver-3050U-2-3-GHZ-4GB-128GB-SSD-AMD-Radeon-Graphics-Int/
