Abstract
Pivalic acid was unidirectionally solidified in a temperature gradient stage. The microstructure parameters; the primary dendrite arm spacing, λ1, secondary dendrite arm spacing, λ2, dendrite tip radius, R and mushy zone depth, d, were measured for five different growth rates in a constant temperature gradient, G and for five different temperature gradients in a constant growth rate, V. The depending of the microstructure parameters to the solidification parameters (V, G and GV) for pivalic acid were determined by linear regression analyze. The stability constant, σ* was calculated by using the experimental values of R and V. The results were compared with the previous works.
