Opis:: The paper presents mechanical and physical properties measured in static conditions, and some properties determined in dynamic conditions, of plates of new nano-composite bainite-austenite (NANOS-BA) steel to be used for construction of armours. Firing tests of NANOS-BA steel plates fixed on a base plate of RHA (Rolled Homogenous Armour), Armox 500T and Armox 600T steel, carried out by means of 12.7 mm B-32 projectiles have demonstrated that in the conditions of tests, NANOS-BA steel shows better protective properties than 500BHN and 600BHN – grade commercial plates. NANOS-BA steel plate of minimum 5 mm thickness has protected Armox 500T and Armox 600T plate from piercing. Quantitative effects were assessed of firing the NANOS-BA steel plates of 50 x 50 mm and 100 x 100 mm surface dimensions, and thickness in the range of 5÷10 mm, as well as sets of the NANOS-BA steel plates of 100 x 100 x (4÷8) mm dimensions, arranged in layers on the base plate. It was determined that ballistic limit V50 for NANOS-BA plate of 6.0 mm thickness, for the 7.62 x 51 mm M61 AP (Armour Piercing) projectile, amounts to 797±10 m/s. Based on the analysis which compared results of tests carried out with the application of various parameters it was estimated that the value of V50 obtained for NANOS-BA steel is higher than the parameters of the highest grade steel plates offered in the global market. The tests imply that NANOS-BA steel is a prospective material for armour construction which can enable to reduce weight of armours and/or to improve their protective parameters in comparison with the presently used structures. Due to very high protective capability, monolithic plates of NANOS-BA steel can be used as one of the layers of the composite armour.

Opis:: Results of tests of mechanical properties and resistance to perforation with small-calibre armour-piercing projectiles for new designed grades of nano-precipitates hardened steels have been presented. The results comprise of mechanical properties essential for materials used in armour and microstructure which influences the mechanisms of piercing. Plate segments of high-alloyed maraging steels and low-carbon Ni-Mo steels were produced using semi-industrial lines for melting, casting and thermo-mechanical treatment. Plate segments were produced with the use of different parameters of final heat treatment in order to achieve a wide range of mechanical properties. Preliminary assessment of the protection capability concerning piercing was carried out based on the results of firing tests with 12.7 mm B-32 incendiary projectiles at square steel plates of 50÷150 mm in dimension and of 5÷10 mm in thickness placed on an RHA (Armox 500T and Armox 600T) "witness" plate. A minimal thickness of plates which protected the "witness" plate and did not fragment was determined. The microstructure in the area of the projectile impact was examined. The usability of newly designed grades of steel in layered armour and the possibilities of the production of these plates from the steel in domestic steel plants were pointed out.

Opis:: The paper includes results of firing tests of the steel plates with nano-structures, i.e. bainitic NANOS-BA® and maraging of size 50x50x5-10 mm, 100x100x5-10 mm and 150x150x5-10 mm, placed on the armour plate RHA (Rolled Homogenous Armour) type Armox 500T or Armox 600T of size 500x500x10 mm, so called "witness plate". There are also presented results of firing tests of the composite space panels CAWA-3+ and CAWA-4 for protection of light armoured vehicles against the anti-tank ammunition type B-32 of 12.7 mm and 14.5 mm calibre. The space panels of size 3300x17.2-22 mm and 254x300x17.2-22 mm were placed at the distance L< 150 mm from the protected thin armour RHA type Armox 500T of 8 mm thickness. These panels included, among others steel plates with nano-structures (of size from 150x150x5-10 mm to 300x350x7-8 mm), i.e. bainitic NANOS-BA® and maraging, armoured steel plates and light metal plates. Effective stopping Af se projectiles in the tested panels was achieved without any traces of the projectile impact on toe RHA plate of 8 mm thickness.

Panele przestrzenne o wymiarach 300x300x17.2-22 mm i 254x300x17.2-22 mm umieszczono w odległości L < 150 mm od ochranianego cienkiego pancerza RHA typu Armox 500T o grubości 8 mm. Panele te zawierały między innymi płyty ze stali nanostrukturalnych (o wymiarach od 150x150x6-10 mm do 300x350x7-8 mm), tj. bainityczne (NANOS-BA®) i maraging, stalowe płyty pancerne oraz płyty z metali lekkich. Uzyskano skuteczne zatrzymanie tych pocisków w badanych panelach bez śladów uderzenia pocisku na płycie RHA o grubości 8 mm.
