スクレイパーを装着した双ロールキャスターによるクラッド材の作製

抄録

Casting of a clad strip consisting of AM60 and AZ121 magnesium alloy was tried using an equal diameter twin roll caster with a scraper. The casting speed was 30 m/min and casting was conducted in the oxidizing atmosphere. The AM60 strip was cast using a scraper, and the molten metal of the AZ121 was poured on the scribed AM60 surface. The two-layer clad strip could be cast by one caster. The two layers were bonded strongly at the interface. The interface was clear. It was estimated that the AM60 was not melted by the molten metal of the AZ121.
