Abstract
Large strain inhomogeneity is caused by the shape of deformation zone of die and by the friction between tool and deformed wire for multistage wire drawing processes. The influence on the value of the redundant strain by the use of different partial single reductions during all wire drawing process was observed. This problem is particularly important for TRIP steel wires drawing processes because the strain intensity influences on the speed of retained austenite transformation into martensite.
