Abstract

The succinonitrile (SCN)-Salol alloys for four different concentrations Salol were unidirectionally solidified for five different growth rates in a constant temperature gradient. The microstructure parameters, viz., the primary dendrite arm spacing, λ1, dendrite tip radius, R and mushy zone depth, d, were measured. The dependence of the microstructure parameters on the solidification parameters for SCN-Salol alloys were determined by linear regression analysis. The results are compared with theoretical models and published data. © 2003 Elsevier Science B.V. All rights reserved.
