Hot flow stress models of the steel C45 [PDF]
Metalurgija, 2015 Flows stress of the steel C45 were predicted on the basis of experimentally obtained flow stress curves, using uniaxial hot compression tests on the plastometer HDS-20, by two completely different types of mathematical models, moreover with comparison to

Research the Dimensional Accuracy of C45 Steel Ring Forgings Produced by Radial Rolling [PDF]
Materials, 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.
