摘要:
AbstractA previous treatment of nucleation in gas atomised liquid aluminium alloys has been extended to model more realistically the cooling conditions in a gas atomiser. Previous predictions of the phase which will predominantly nucleate in powder particles, as a function of powder size and composition, are reinforced. Predicted undercoolings are now slightly higher than in the earlier work. Results from this work are compared with recent experiments.MST/1013
