Correlation of Properties of Materials to Debye and Melting Temperatures

摘要: Many solid state properties are correlated to simple parameters like the atomic mass, interatomic distance and some measure of strength interaction, e.g. melting temperature Tm or Debye θD. Such empirical relations investigated for elastic properties, temperature, thermal expansion, vacancy formation energy, grain boundary surface cohesive heat fusion, activation energies bulk, boundary, dislocation pipe diffusion, viscosity, energy creep, recrystallization other properties. When experimental data available, both elements diatomic compounds (alkali halides, oxides, carbides, III-V semiconductors) considered. The correlations Tm, θD(T = 0) a high effective θD compared. It is found that all practical purposes gives best correlation. For compounds, average mass not uniquely defined various averages discussed. purpose paper only present but also give short account possibilities calculate considered using theory in its most advanced state.
