Sažetak

The paper presents an experimental analysis of the effect of single draft magnitude in the multi-stage drawing process on the mechanical properties of the wire, and a theoretical process analysis aimed at identifying the causes of the variations in mechanical properties, made using Drawing 2D, a FEM-relying software program of high manganese TWIP steel rolling and stamping processes. It was found that wires drawn with small partial drafts (G_p%=11 %) had a larger plasticity reserve, as defined by the R_0.2/R_m ratio, as compared with wires drawn with large partial drafts (G_p = 26 %). A drop both in tensile strength R_m and in proof stress R_0.2 was also found to occur after a total draft of G_c = 80 % had been exceeded, which was caused by the “strain softening” phenomenon.
