Литье и прокатка магниевых сплавов

Abstract

The paper is concerned on the production of magnesium alloy strips by Twin-Roll-Casting and their subsequent hot rolling to a final thickness of ≥ 1 mm. In this connection, specific characteristics of magnesium and of the used alloys are discussed. Subsequently, the deformation behavior and the possibilities to its increase are introduced. Additionally, the production technology of hot strips and the properties obtainable are presented on the example of the alloys AZ31. Mechanical properties and the development of microstructure as well as their change during the way of production clarify the development process. Special attention is paid to the thermal pretreatment of the casting condition with local deformation.
