The specific properties of TRIP steel can be obtained by the occurring the effect of additional plasticity during transformation of metastable retained austenite into martensite caused by plastic deformation process. Research carried out for highly alloyed austenitic steels with TRIP effect proved the influence of strain intensity, chemical composition and deformation temperature on efficiency marteniste transformation. In the work research concerned with the influence change of drawing speed on retained austenite amount in drawn wires structure was shown. In available literature there are no publications concerned with the influence of wire drawing process parameters on the structure evolution the medium carbon TRIP steel wires. Research shown in the work was realized with the assumption that the strain intensity is determined by scheme of single and total reductions, and the value of strain rate is a result of used in wire drawing process drawing speed.
