Mechanical and Physical Properties of Pure Metals - Relation to inter-atomic Bond Forces
Alfred Buch, Haifa, Israel
ABSTRACT Certain properties of pure metals are dependent on bond forces, change periodically in magnitude with continuously ascending atomic number, and show some regular change of magnitude for metals belonging to the same subgroup of the Periodic Table. The increase and decrease of the elastic moduli with continuously ascending atomic number proceeds simultaneously with similar directions of change in Mohs Hardness, the latent fusion heat and the specific heat capacity. An example is the linear relation between the Young's modulus and the Mohs hardness of fcc-metals or the linear dependence of the Mohs hardness and the latent fusion heat. The dependence of specific heat capacity can be also linear for some fcc and bcc metals. For metals belonging to the same subgroup there exists a similar magnitude sequence for the Young's modulus and for the corresponding Mohs hardness, and a reverse magnitude sequence for the Young's modulus and the thermal expansion coefficient.
