Abstract
The synthesis of a composite material by thermal explosion in a reaction mixture of Ni + Al + Cr2O3 was studied. The thermodynamic parameters of combustion of the systems studied were estimated to predict the composition of the inorganic products (condensed or gaseous) of self-propagating high-temperature synthesis and calculate the adiabatic combustion temperature. It is shown that the synthesis process involves competing reactions in the sample volume which are responsible for the formation of a multiphase product. The influence of the content of Cr2O3 in the reaction system on the strength characteristics of the product synthesis was studied. The microstructure of the synthesized samples was examined, and their micro-hardness, toughness and residual porosity were determined. The possibility of obtaining a homogeneous material based on NiAl intermetallic compound containing dissolved chromium and chromium oxide nanoparticles is shown.
