Abstract Scope |
Twin-roll casting is a process in which liquid metal is introduced into a narrow gap between rotating rolls, where it first solidifies and is then deformed to produce thin sheet. The complex microstructural features resulting from the combined solidification and deformation have a profound effect on the properties of the final product.
We present a computational model of the TRC process that accurately predicts the final microstructure and crystallographic texture through the cast strip, in addition to measurable process outcomes, such as roll separating force and forward slip. We demonstrate the validation of the model by a series of industrial trials, where AA1050 aluminum alloy was cast under a variety of processing conditions. The model allows us to examine the interplay of solidification, shear, and compression through the sheet thickness as they produce the final microstructure and crystallographic texture. |
