CRYSTALLOGRAPHIC TEXTURE DEVELOPMENT OF AS-CAST 3105 ALLOY PRODUCED BY St/Cu SHELL PAIR

摘要

Altering operational casting parameters has limited effect on increasing productivity of twin roll cast (TRC) alloys. Further improvement can be accomplished by enhanced heat transfer between shell material and solidifying metal. In that respect copper alloys are commercially utilized in twin roll casting technology. However, it can be easily predicted that microstructure and texture development would be different than those produced by conventional steel shells. Present study investigates crystallographic texture development of as-cast 3105 alloy produced by St/Cu shell pair. Pole figures were employed to characterize the dominant texture. Complimentary studies were performed by macro and microstructural investigations.
