Abstract. The elastic interactions of two CdSe structural modifications (cubic and
hexagonal) were studied for the comprehensive analysis of polycrystalline cadmium
selenide parameter degradation. The system studied was modeled as a hexagonal matrix
with a spherical inclusion of the cubic modification where elastic strains were calculated
at the matrix-inclusion boundary. The fulfilled analysis permitted, besides the main
problem solution, to obtain the elastic constants μ and K for two modifications of CdSe,
which essentially supplies the known material characteristics. The top value of the
pressure, P0 normal component, achieves 109
Pa, which excesses over the known values
of P0. The results achieved may be useful for the further investigations of the degradation
transformations in a polycrystalline biphase systems.
Keywords: structural transformations, elastic parameters, cadmium selenide.
