Plastometric Modelling of the E635M Zirconium Alloy Multistage Forging Process

Abstract

The purpose of the process was to develop the guidelines for the new technological process of producing E635M zirconium alloy bars, including the conditions and schemes of deformations in individual open-die forging operations on a hydraulic press. The determined range of hot plastic deformation parameters (temperature, strain, strain rate) will contribute to the intensification of the plastic flow process in individual technological forging operations at a lower total energy consumption, with simultaneous homogenization of the structure in finished bars. Plastometric modeling of the process of hot forging square cross-section forging for industrial conditions and according to a newly developed scheme was carried out within the study. The examination was performed using the Pocket Jaw module of the plastometric device Gleeble 3800.
