Özet

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, lambda(1), 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. (C) 2003 Elsevier Science B.V. All rights reserved.
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, l1; 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.
