Показано, что превышение динамической твердости над статической может быть описано с помощью коэффициента динамичности, представляющего собой функцию свойств материала и условий испытаний. В рамках дислокационной теории показановлияние скорости деформации на величину твердости, при этом отличие значений коэффициента динамичности объясняется разной кристаллической структурой исследуемых материалов. С помощью прибора ИПМ-1К получены экспериментальные диаграммы динамического нагружения различных металлов: стали, алюминия, бронзы, латуни, меди, титана. Предложена методика калибровки динамических твердомеров для расчета статической твердости по Бринеллю без использования эталонных мер твердости.</p></abstract><trans-abstract xml:lang="en"><p>Problems of measurement of hardness by the dynamic indentation method are discussed. It is shown that an excess of dynamic hardness over static one can be described by the coefficient, which is a function of material properties and test conditions.In framework of the dislocation theory the influence of strain rate on hardness value is shown, and the difference in ratio between static and dynamic hardness can be explained by different crystal structure of materials.With the help of the device IPM-1K the experimental diagrams of dynamic loading of various metals: steel, aluminum, bronze, brass, copper, titanium were obtained. A method of calibration of dynamic hardness testers for calculation of the Brinell hardness without using standard hardness test blocks was proposed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>твердость</kwd><kwd>металлы</kwd><kwd>индентирование</kwd><kwd>кристаллическая решетка</kwd><kwd>динамическоенагружение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hardness</kwd><kwd>metals</kwd><kwd>indentation</kwd><kwd>crystal lattice</kwd><kwd>dynamic loading</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Tabor, D.
