The concept of the Mie potential and a new understanding of the nature of the forces acting between structural components of a substance (atoms, ions, molecules) are used to develop a model allowing for the effect of the thermal action of particles (the thermal field) on the chemical bonds in the substance. The new concepts on the chemical bond are used to derive a formula for the theoretical strength of materials in a wide temperature range. The calculated values of the theoretical strength of Al2O3, SiO2 (glass), and SiC at 293 K agree well with the actual strength of whiskers. The established temperature dependence of the theoretical strength of Al2O3 is adequate to the temperature dependence of the actual strength of whiskers. The theoretical strength is a physical parameter of a material and can serve as a comparative characteristic for choosing a material for specific service conditions. [ABSTRACT FROM AUTHOR] |
