Effect of Extrusion Size on Forming Process in Equal Channel Angular Pressing

Abstract:

In order to meet the industrial demands for large-sized bulk ultrafine-grained materials, which were prepared by severe plastic deformation, the law curves of equivalent strain, equivalent stress and load of different-sized extrusions had been gotten by the finite element simulation of ECAP. The extrusion size has little effect on the values and distribution law of equivalent strain as well as the values of equivalent stress. With the increase of extrusion size, the distribution uniformity of equivalent stress decreases, and the extrusion load increases. Although the ECAP of the large-sized extrusions improve the requirements of mold and equipment, the chunk of evenly ultrafine-grained materials can be obtained by multiple passes.
