Evolution of Metallographic Parameters during Horizontal Unidirectional Solidification of Zn-Sn Alloys

In the present research the horizontal directional solidification of Zn-Sn alloys (Zn-4wt.%Sn, Zn-6wt.%Sn, Zn-10wt.%Sn and Zn-30wt.%Sn) was carried out by extracting heat in two opposite directions. For this purpose, ceramic molds, a muffle, a horizontal furnace with two heat extraction systems at t...
