Zone Melting for Alloy Refining

Zone melting directional solidification is a metallurgical process used to move a narrow molten region through a crystal, usually a bar-shaped sample. A furnace travels along the rod, so the molten zone moves from one end of the bar to the other. This controlled motion changes how material forms as it solidifies.

Zone melting directional solidification is a metallurgical method employed to prepare stable phases in solid materials. During the solidification process, a melted alloy cools into various phases that form the solid. Using a directional solidification furnace, the process of phase formation and stabilization inside a solid material, is well cont...
