This is a new type of high-strength material. Deformation mechanism of TWIP steel ? twinning - provide a unique mechanical properties. That predisposes this steel as one of the main structural materials in the applications for car-bodies design. During the experiment (stretching test of shaped samples with cut-out circular segments of constant radius by semispherical punch) was carried out measurements to obtain construction points of final limit curves. The results of the experiment were also used to extend the evaluation method for final limit diagrams of high-strength materials. On the basis of them was designed new 2D diagram with coordinates m?-SFLC. During measurement was used optical contact less system ARAMIS. The results serve as a basis for further testing of TWIP steel, as well as a starting point about improving the modified evaluation method of the final limit diagrams.
