Abstract
This paper presents several bimetallic operations (forward, backward and radial extrusion). In forward extrusion sleeve aluminium and core copper material were deformed in 90° die. Experimentally obtained results (load-stroke diagram) were compared with analytical calculations. Backward extrusion was performed in a φ30mm die with φ18.9mm punch. Same material composition as in forward extrusion was used (outer aluminium and inner copper material). Results obtained in experiment (load-stroke diagram) were compared with numerical simulation performed in Simufact Forming 9.0. In the end, numerical simulation and experimental investigation of radial extrusion of gear-like element is presented
