PROTAC 500 - Armored steel of new generation

In this work we studied the response of newly developed armored steel plates PROTAC 500 to the ballistic testing with armored piercing bullets with a core of tungsten carbide, charge 7.62 mm. Interactions between the bullets and the steel plate was investigated by standard metallographic and mechanical testing methods. We were interested in the geometric features of interaction, the phenomenon of adiabatic shear bands (ASB), cracks and local failure, local melting and interaction of the components and plate with metal balls fragments in the melt, rate of deformation and the steel hardening.
