FeCrAl alloys have good oxidation resistance at elevated temperature owing to the formation of a continuous Al2O3 surface film, which acts as an oxygen diffusion barrier. The aim of the present study was to investigate the early stages of protective oxide layer formation and its growth on specially prepared commercial FeCrAl alloys, Kanthal AF (K-A...

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 geo...
