Abstract
Sintered compacts of copper and a 50Cu–50Fe mixture have been plastically deformed to large strains (total strain ɛt=13·8) by cyclic extrusion and compression. The hardness changes after deformation indicate that no further work hardening occurs with either material when ɛt>4·6. With copper, strain accommodation at large strains would appear to occur solely by dynamic recovery and recrystallisation. With the Cu–Fe mixture, shear banding is still found at the highest strains used. MST/1609Keywords
