Research the Dimensional Accuracy of C45 Steel Ring Forgings Produced by Radial Rolling. [PDF]
Materials (Basel), 2023 The rolling process of rings is a commonly used method for producing annular forgings. There are two primary types of this process: radial-axial rolling and radial rolling. This article presents the research results regarding the latter, in which obtaining a product with the assumed dimensions constitutes a major problem.

Flow Curves for C45 Steel at Abrupt Changes in the Strain Path
CIRP Annals - Manufacturing Technology, 1988 Many industrial forming processes involve a non-straight strain path. In general, a deviation from a straight strain path is accompanied by a change in the flow curve. The deviations that lead to a reduced flow stress are especially important because they may lead to instability.
