Physical hardness of kinetic macroindentationof materials,theory and methods of determination, relationshipwithstandard hardness. Application prospects
Abstract
The physical properties of force diagrams of kinetic macroindentation of materials bytheBrinell sphere are studied. Theoretical and experimental substantiation of physical conceptsofthe function and number of hardness, new analytical methods for analyzing data fromtheprocess of kinetic macroindentation. Universal physical unit of material macrohardness. Method for determining the function and number of physical macrohardness of the kineticindentation of the material. The reason for the size effect in standard empirical methodsfordetermining hardness is shown. A correct physical method for comparing and translatingthehardness values of different scales is proposed. To analyze the force diagrams obtainedbydifferent indenters, to determine the correct values of the physical and empirical hardnessofmacroindentation, physical algorithms and formulas have been developed. The prospect ofusing the research results for different ranges of kinetic indentation, improving the ISO14577standard is discussed. An example of using the physical parameters of hardness in universal methods for calculating the parameters of strength, fatigue and durability of materials.
