Ductile Fracture Prediction in Cross-Wedge Rolling of Rail Axles. [PDF]
Materials (Basel), 2021 In the process of cross-wedge rolling, axial-symmetric forgings are formed using wedge tools. These tools may be flat- or roll-shaped. This article presents two methods of cross-wedge rolling of rail axles, traditional and multi-wedge, as well as their advantages and disadvantages.

Contact Pressure Measurement System in Cross Wedge Rolling [PDF]
AIP Conference Proceedings, 2010 In the cross wedge rolling process (CWR), plastic deformation is geared by a driving torque transmitted by friction on die surface. Friction plays a role which has to be further identified in this metal forming process. The local contact pressure between

Novel damage calibration test based on cross-wedge rolling
Journal of Materials Research and Technology, 2021 This article presents a new calibration test for damage functions that uses the cross-wedge rolling method (CWR). In this test, the forming conditions were altered by applying wedges with decreasing forming angle on conical-cylindrical samples.
