| Abstract: | Copyright © The Author(s) 2020. The effect of dilute solute additions on growth restriction in binary Cu alloys have been assessed at different degrees of superheat. Columnar grain length values from Northcott’s work [1] for binary Cu alloys were plotted against the corresponding undercooling parameter (P), the reciprocal of the conventional (Qconv.) and true (Qtrue) growth restriction factor [2] values. It was found that there was no correlation between the columnar grain length values and P, 1/Qconv. and 1/Qtrue values for different solutes and cast at the same degree of superheat. Unlike P, Qconv. and Qtrue values, the heuristic growth restriction parameter (β) [3] modelling framework in conjunction with the critical solute content (C*) for growth restriction fitted well to binary Cu alloys. |
