In laboratory of Plastic Deformation Materials (ISMAN), a new scientific direction has been developed: SHS in conditions of shear high-temperature deformation. Combination of SHS process and high-temperature synthesis makes it possible to produce materials and products based on refractory compounds.
The report presents the results of development of the SHS-extrusion process to obtain long products from brittle and hardly deformed powders of refractory inorganic compounds. Experimental studies of rheological behavior of SHS materials and their ability to plastic deformation at high temperatures are discussed. Structure and properties of extruded SHS materials are presented. The main aspects of mathematical modeling of SHS-extrusion and pressing are considered. Examples of practical application of the developed SHS extrusion method for producing long products from new multifunctional materials — composite ceramic materials with nanoscale structural elements, materials based on MAX phase of the titanium-aluminum carbon system, materials based on intermetallic compounds — are given.
