Demonstration of a high-performance continuous casting process for cobalt alloy ASTM F75

Abstract

A modified horizontal high performance continuous casting configuration was investigated by the introduction of a mechanically durable and thermally insulating zirconia-based break-ring and the application of a copper-beryllium die for the casting of cobalt alloy ASTM F75 (Co: balance, Cr: 27 wt%, Mo: 5 wt%). Successful casting was demonstrated with an 8 mm diameter rod with good physical properties and a metallic phase structure and distribution consistent with the standard.
