  • Hardness and deformation properties of solids at very high

    This paper describes an experimental study of the deformation and strength properties of refractory solids at temperatures up to 2000 °C It is difficult to make direct stressstrain measurements at elevated temperatures on small specimens of these materials, and consequently the strength property measured was in dentation hardnessWith brittle solids the high hydrostatic pressures around the deformed region are often sufficient to inhibit brittle fracture Under these conditions both indentation and scratch hardness are essentially a measure of the plastic rather than the brittle properties of the solid This provides a simple physical basisThe hardness of solids | Semantic ScholarWith brittle solids the high hydrostatic pressures around the deformed region are often sufficient to inhibit brittle fracture Under these conditions both indentation and scratch hardness are essentially a measure of the plastic rather than the brittle properties of the solid This provides a simple physical basis for the Mohs scratch hardnessThe hardness of solids IOPscience

    The structures and properties of solids can be classified according to the forces that hold the atoms together Ionic solids are held together by the mutual attraction between cations and anions Covalent network solids are held together by an extended network of covalent bonds (Think of diamonds💎) Molecular solids are held together by weak• Solids and liquids can be described by their properties • Some properties of solids are colors, shape, ability to roll or stack, hardness, magnetic attraction, and whether they float or sink • Some properties of liquids are color, tendency to flow, degree of viscosity or fluidity, whether they are miscibleSecond Grade Solid, Liquid & Gas INTRODUCTIONFurther it is well known that the hardness is closely related to the elastic properties of crystals Ionic charge depends on the outermostshell electrons of an atom Thus, there must be a correlation between ionic charge and the properties of solids 4Bulk modulus and hardness of chalcopyrite structured solids
