Texture and its Influence on the Mechanical and Ballistic Properties of Steel Armor Plates

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 he plates as a function of the intensity of the texture, in particular the (112)+(iii) type, are presented and discussed.

Effect of Tempering Temperature on Microstructure, Texture and Mechanical Properties of a High Strength Steel

“…However, the effect of texture on the properties of hot rolled, quenched and tempered plates has been less explored. In an earlier investigation on 5 Ni armour steel, Hu et al (1980) have demonstrated that the ballistic performance of the strongly textured plates is substantially superior to that of the random textured plates of the same hardness.…”

“…6). This appears to be consistent with the intensity of the texture which is correspondingly lower in the present Ni-Cr-Mo plates (Table X).…”

Texture evolution in high strain rate deformed Cu–10Zn alloy

“…The knowledge of high strain rate deformation response on the evolution of microstructure and texture is of great importance, as a large number of processes involve high strain rate deformation and the resulting microstructure and texture influence the performance of the product quite significantly [1]. Although some authors have reported that the effect of strain rate on deformation texture is minimal as the choice of slip systems in FCC crystals is not sensitive to the strain rate [2], some contradicting observations have been reported.…”
