Interfacial reaction between zirconium alloy and graphite mold/yttrium oxide ceramic mold [PDF]

China Foundry, 2014
Zirconium alloys are active in the molten state and tend to react with the mold during casting. The casting technology of zirconium is not yet well established; especially in selecting the mold materials, which are difficult to determine.
