The main subject of the present work is investigation of possibility of extension of classical orbital forging technology to obtain more cost effective forging process. Orbital forging is the process used for forging of shaped parts by applying the incremental forging method. Results of simulation of orbital forging are compared in the present work with the result obtained from a conventional forging process. 3D finite element (FE) simulations are used in the present project to evaluate the capabilities of the orbital forging process and proper die design, and to predict the forging loads the. Selected results of simulations are presented in the paper. These results are the basis for the further comparison and discussion about possible modifications of conventional orbital forging approach.
KOBO extrusion of metals and alloys strongly activates the point defect generation processes, as a result of which they reach a concentration exceeding the equilibrium level by many orders of magnitude. This leads to significant acceleration of diffusion phenomena which in heat-treatable alloys may cause disturbance of the thermodynamic equilibrium between the solid solution decomposition and dissolution of precipitates. In this work, measurements of mechanical and electrical properties and structural observations Cu1Cr0.1Zr alloy subjected to low-temperature KOBO extrusion at different stages of multi-variant heat treatment were conducted. In addition, the geometry of the extruded alloy's flow zone was analyzed and the obtained results made it possible to assess the effectiveness of experimental procedures, including product formation with high extrusion ratio λ, aimed at achieving of high and thermally stable functional properties of the material.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
