Structural Organization of Steel to Ensure Special Equipment Safety

چکیده
Introduction. At present, great success has been achieved in the field of creating effective protective materials. Various non-metallic, metal-ceramic, and also composite materials act as armor elements. However, most elements vehicles personal equipment (PPE) are steels that, along with high ballistic resistance, have a mass. In this regard, relevance article is related to possibility lightening typical when using material that structural organization like natural ferrite-martensite (NFMC). The work objective evaluate prospects steel an oriented structure exposed high-speed concentrated impact power comparison used. Materials Methods. features disadvantages revealed, comparative analysis carried out NFMC. assessment 14G2 microstructure state different hardening temperatures (730 °C 760 °C) was by method microstructural analysis. relation topic study, for use low-carbon ferritic-martensitic were shown based on laws fracture mechanics their experimental data obtained sample dimensions 150 × 44 7 mm after testing bullet resistance cartridges core armor-piercing tungsten made SVD rifles AK-74 assault 7.62 5.45 caliber, respectively. Results. possibilities evaluated homogeneous heterogeneous such nature development fracture, expressed deceleration crack during delamination at boundaries. When formed, expends energy changes its direction, which subsequently leads complete stop process. Discussion Conclusion. materials, associated thickness element laborious process obtaining sandwich, respectively, can be solved steel. presented indicate higher due special propagation mechanism, relevant armored vehicles. This makes it possible reduce total mass combat decrease while maintaining required class loading, will increase mobility fuel consumption.
