INFLUENCE OF EQUAL-CHANNEL ANGULAR PRESSING ON CHANGES IN THE ...

a torsion-breaking machine MI40KU was used. Standard samples, cylindrical in shape (diameter of the working part 3 mm, length 15mm), were used. The stretching rate of the samples was 0.5 mm/min, which corresponded to a strain rate of 0.56⋅10−3 sec−1. All samples were examined in their midplane to avoid the influence of pe-ripheral regions. ................
