Microstructural Characterizaton and Effects on Mechanical Properties of Boron Added Armor Steels

Abstract

The performance of steels depends on the properties associated with their microstructures, that is type, volume fraction, form factor, size and the area distribution of the various phases involved. Because all the phases in steels are crystalline, steel microstructures are made up of various crystals, sometimes as many as three or four different types which are physically blended by solidification, solid-state phase changes, hot deformation, cold deformation and heat treatment. Each type of microstructure is developed to characteristic property ranges by specific processing routes that control the microstructural changes. Thus processing technologies are used to tailor the final microstructure.

The Influence of Single and Double Steel Plate Hardness on Fracture Behavior after Ballistic Impact

“…Ballistic resistant materials (armor) are material that can withstand the pace of projectile fired from guns. It's developed and used in military or civil as the main construction and additional surface protection [1], and metallic armor is the most mature class of armor materials and is still widely used for ballistic protection today [2]. Armor material has long been developed and has been made to contour maps for ballistic performance of thick metallic armor as reported [3].…”
