Abstract Scope |
Composite ring rolling could bring substantial material, cost and energy savings and allow for lighter weight components, by joining concentric rings with different material properties. For there to be any possibility of achieving a material bond, an interference fit between the rings must be maintained. In this paper, a force equilibrium-based model is introduced to predict when such a fit is possible. This model, for radial composite rolling, predicts a limit to the flow stress of the inner ring relative to the outer ring; suggesting a maximum ratio of about 160%. It also shows that the inner tool’s diameter must often be significantly smaller than the outer tool’s. The model was successfully tested in four composite ring rolling experiments with two grades of Aluminium alloy, 1050 and 6063, and different tool sizes, suggesting it could be a valuable new guide to designing composite ring rolling processes. |
