Abstract
A heterogeneous material obtained by means of cold gas dynamic spraying with subsequent laser processing is studied. The reasons for reduction of the particle size of boron carbide B4C under the action of a laser beam and the chemical composition of the material containing the "lost" material of B4C particles are examined. A mathematical model, which takes into account the dissolution of B4C particles and the presence of a chemical reaction, is developed. The elastic properties of the deposited heterogeneous material are analyzed with the use of continuum approaches that describe heterogeneous media and are based on averaging of the original stochastic equations.
