Sažetak
Study shows the influence of stretching rate on the tensile properties for two low carbon steels during cold plastic deformation. Studies were carried out at laboratory conditions at room temperature with a static tensile test, at stretching rates ranging from 5 to 30 mm / min. Influence of the stretching rate on the elongation (A), tensile strength (Rm), yield stress (Re) and the ratio Re/Rm were analysed by MATLAB software. For both steels, yield stress and tensile strength increase with the increase in stretching rate, while the elongation decreases for both steels. The ratio Re/Rm for niobium microalloyed steel remains constant. It can be concluded that both steels are strain rate sensitive, and that only Re/Rm ratio cannot be used to determine the strain rate sensitivity of the steel.
