After annealing in two-phase α+β field the material had another type of β-grain structure, and also was pierced through; however, the bullet was completely stopped inside the plate (Fig. 16d). Near the top of the bullet channel some deformation traces were found (Fig. 16e), and in the bottom ASBs and cracks were present as well (Fig. 16f). After SRHT the bullet did not penetrate through the plate, and a bulge of about 2-2.5 mm height formed on the rear side (Fig. 16g). ASBs were observed both on the top (Fig. 16h) and bottom (Fig. 16i) sections, that indicates on the localization of plastic flow both in top (thermally hardened) and bottom (ductile) layers. In other words, hardened by SRHT layer had relatively good reserve of general ductility, despite its higher strength, and its level of ductility was rather close to that of the material annealed at temperatures of α+β field, whereas the alloy with coarse-grained lamellar microstructure had too low properties.
