Abstract

By appropriate thermomechanical processing treatment in the austenite region of a medium carbon 5Ni steel, three different types of textures, each with various degrees of intensity, have been produced in the quenched-and-tempered high-hardness steel armor plates. The various mechanical properties, including tension, through-thickness tension and compression, impact, fatigue, and fracture toughness, together with the ballistic performance of the plates as a function of the intensity of the texture, in particular the (112)+(111) type, are presented and discussed.
