Abstract

Four specimens of the zinc eutectic Composition (95% Zn + 5% AL) were prepared by casting method, the first specimen was air cooled and the second was water cooled. They revealed irregular Lamellar-eutectic microstructures (L.E.M.). The third specimen was sliced into many Samples with constant thickness, but with variable solidification velocity by using a movable tube furnace, which resulted in a regular (L.E.M), this process revealed that: (n) in the equation (λnV=K) was equal to (2.2). However, our finding was different from those obtained by TILLER, which stated that (n=2) But this result falls into an agreement with the modification of LESOULT, the result was in good agreement with the experimental data which governed by relationship.
