a Simulated liquid channel morphology during dendritic growth of the melting zone fabricated with ER2319 (top) and ZCASW (bottom) fillers. The six panels in each row correspond to the different temperatures. b, c Simulated solute distribution of the melting zone fabricated with the ER2319 filler and the ZCASW filler at 882 K. d Solute distribution along line AA’ in (b) and line BB’ in (c). e T-(fs)1/2 curves and cracking susceptibility indexes calculated from the PF simulations for the melting zone fabricated with the ZCASW (blue) and the ER2319 (orange) fillers (CSI represents cracking susceptibility index).
