Sažetak
The engineers of the biggest Slovenian steelwork ACRONI d.o.o., firms SAAT d.o.o. and PROTAC d.o.o. have been designed and developed, in cooperation with domestic and foreign institutions of science, a new generation of armored steel. Armored steel PROTAC 500 belongs to the group of high strength low alloy (HSLA) steels. It is made in steelwork ACRONI d.o.o. by the standard industrial procedures. The relevant mechanical properties of that steel are achieved by corresponding heat treatment procedures: quenching and tempering. The presented work studied the response of new generation armored steel plates PROTAC 500 to the ballistic testing with armored piercing bullets with a core of tungsten carbide, charge 7.62 mm. However, the interactions between the piercing bullets and the armored steel plate were also investigated. The most obvious and significant phenomena in penetrating the piercing bullets in steel target PROTAC 500 are strain hardening of steels, the appearance of cracks and local failure, adiabatic shear bands (ASB) with related phase transformations, and melting as well as alloying at the interface between bullet and steel plate.
