DEVELOPMENT OF A NEW TYPE OF HETEROGENEOUS ARMOR ALUMINUM AND TITANIUM-BASED MATERIAL OBTAINED USING EXPLOSION WELDING AND STUDY OF ITS PROPERTIES

The study objective is to obtain a new type of heterogeneous armor material based on aluminum and titanium by explosion welding, which has improved tactical and technical characteristics compared to monometallic armor materials. The paper tasks are to develop a technology for making the specified composite material and to study its basic physical and mechanical properties. The research methods used are comparative analysis at the stage of determining the efficiency of work, mathematical calculation of explosion welding parameters to obtain the composite, assessment of the macrostructure of the material, assessment of the quantitative chemical composition of the composite metal base and its edge zone, and assessment of its bullet resistance. The novelty of the work is in the application of a new reinforcement scheme, which increases the complex of properties of armored material compared to monometallic armor. The study results show that the materials developed are in demand both in Russia and abroad; complex heterogeneous aluminum-based armor structures currently show the best efficiency; explosion welding is the most relevant way to create a composite material. The heterogeneous armor material is obtained, which makes it possible to reduce the weight of armored vehicles by 20-25%, provided that the specified level of bullet resistance is maintained in comparison with monomallic aluminum armor.
