COMPOSITE METAL MATERIAL WITH INTERMETALLIC HARDENING AND ADJUSTABLE LEVEL OF PROPERTIES

The study objective is to develop composite metal materials with intermetallic hardening based on aluminum and titanium alloys that combine the required level of mechanical characteristics. The tasks to which the paper is devoted are to develop a method for creating a bulletproof composite material that provides the ability to control its structure and level of properties over a wide range. The research methods used include mathematical calculation of explosion welding modes [1] to obtain a composite material based on aluminum and titanium alloys, heat treatment of the resulting composite and evaluation of the mechanical properties of the material. The novelty of the work is in the application of patented technical solutions that make it possible to create composite bulletproof metal materials by explosion welding, including new methods of reinforcement and the formation of reinforcing intermetallic layers of adjustable thickness in the composite structure. The study results show that these materials are in demand both in Russia and abroad; new bulletproof metal materials are being created; the current direction in the field of making bulletproof materials is the development of heterogeneous composite materials. A composite is obtained which structure contains perforated sheets in order to avoid delamination of solid intermetalloid layers under shock loads. This will limit the spread of cracks, preserving the integrity of the material under dynamic impact. By adjusting the thickness and number of layers, the properties, density, and bullet resistance of the material can be widely controlled.
