Vertical and Horizontal Directional Solidification of Zn-Al and Zn-Ag Diluted Alloys

Zinc Aluminum and Zinc Silver alloys were solidified in horizontal and vertical form and the results obtained analyzed Thermal parameters such as the cooling rates the liquidus and solidus interphase velocities and the temperature gradients were determined The velocity, of the liquidus interphase is greater than or sometimes equal to the velocity of the solidus interphase In the vertical setup columnar to equrixed (CET) grain transition was obtained CET does not occur in the horizontal one directional solidification when critical minimum gradients reach values greater than 0 1 K/mm [doi 10 2320/matertrans M2010036].
