Design of nanostructured cermet materials high-speed impact conditions

Abstract

The means of production of nanostructured composite materials by the method of self-propagating high-temperature synthesis (SHS) with the application of pressure to the product of combustion and by the method of intensive plastic three-sided a,b,c deformation are considered. A composite material of combined structure is developed, which is a layer system, one of the layers of which is a product of the exothermic reaction of the Ti-B-Ni system in the form of an interlayer produced by pressing the heated SHS product, and the other layer is inert, the role of which is played by the metal layer. The properties of the developed materials, including the TiB2 + B4C-based ceramic metal, are studied under the conditions of high-speed impact.
