摘要: Abstract Directional solidification experiments have been carried out to study primary dendrite spacing of lead dendrites in Pb-Sn alloys over a very wide range temperature gradient, G , rate, V and alloy composition. Based on these experiments, the spacings, λ, is found not obey correlation λ = KG - b velocity gradient values. For constant decrease as increased, only for high values form AG obtained. Even this case exponent be function velocity. Furthermore, given appears go through maximum
