Analysis of quality of bimetallic rod after extrusion process

In this article, an analysis of extrusion process of bimetallic rod is presented. Cylindrical, two-layered rod made by explosive cladding of the aluminium rod (1050A) and copper pipe (M1E) with appropriate chosen geometry was treated as a charge in the analysed process. In the work an influence of die shape and extrusion ratio on a charge yield in the process was investigated. Theoretical analysis was prepared using commercial package Forge2® based on FEM. Theoretical studies were verified by experimental analysis prepared in the Institute of Modelling and Automation of Plastic Working Processes.
