Diagnostics, Resource and Mechanics of materials and structures Issue 3, 2017 42 Maisuradze M. V. et al. / Investigation of the microstructural banding in steel 4140 The microstructural banding of the 4140 steel is studied. The dependence of the anisotropy index on the bar diameter and sampling location is established in accordance with GOST R 54570 (ASTM E 1268). A relationship between microstructural banding (i.e. anisotropy index) and toughness is shown to exist. A correlation between the
