Показана зависимость свойств поверхностных слоев от абсолютных размеров тел. Полученные при этом выводы могут быть распространены на результаты изучения влияния различной формы твердых тел на их поверхностные и линейно-объемные свойства. Развитие новых технологий и технологический прогресс постоянно ужесточают требования к металлоемкости технических устройств, в результате чего бывает достаточно тяжело обойти возможность появления в особо ответственных деталях усталостных борозд и трещин. В некоторых случаях они могут возникнуть на самых ранних стадиях эксплуатации, т.е. присутствуют в деталях в течение большей части их жизненного цикла. Поэтому для всесторонней оценки работоспособности и ресурса изделий необходимо иметь достоверные сведения об эволюции параметров циклической прочности и долговечности, обладать максимальной информацией о процессе накопления повреждений на всех этапах усталостного нагружения – стадиях зарождения трещин, их развития и, как следствие, разрушения конструкции. Вследствие этого необходимость совершенствования методик усталостных испытаний и выявления закономерностей разрушений является одной из актуальнейших задач технического продвижения. Установлено, что различие деформации у поверхности приводит к изменению способности к деформационному упрочнению, что влечет изменение повреждаемости поверхности и показателей прочности образцов. Подход к масштабному эффекту как явлению рассматривается с позиций различия пластической деформации поверхностных слоев образцов разных абсолютных размеров.</p></abstract><trans-abstract xml:lang="en"><p>The article describes a study into the large-scale effect and properties of surface layers of solids in case of the Al–Mg system (AMg2) aluminum alloy. It demonstrates the dependence of surface layer properties on the absolute sizes of bodies. The conclusions obtained can be extended to studying the influence of different shapes of solids on their surface and linear bulk properties. New technology development and technological advance constantly toughen metal consumption requirements of engineering devices thus making it rather difficult to avoid fatigue striations and cracks forming in critical parts. In certain cases they may form at the earliest stages of operation, i.e. parts run with cracks most of their life cycle. Therefore, comprehensive assessment of their performance and life requires reliable data on the evolution of cyclic strength and durability parameters, and maximum information on the process of damage accumulation at all stages of fatigue loading: stages of crack origin and development leading to structural failure. Therefore, the need to improve the methods of fatigue testing and failure pattern detection is one of the most relevant problems of technical advance. It is established that the difference in deformation at a surface leads to changes in work-hardenability that involves changes in surface damageability and strength performance of samples. An approach to the large-scale effect as a phenomenon is considered from the perspective of the difference in surface layer plastic deformation for samples of different absolute sizes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>масштабный эффект</kwd><kwd>абсолютные размеры образцов</kwd><kwd>физико-механические свойства</kwd><kwd>предел усталости</kwd><kwd>кривая усталости</kwd><kwd>сопротивление усталости</kwd><kwd>микроструктура</kwd><kwd>полосы скольжения</kwd><kwd>повреждаемость поверхности</kwd><kwd>относительная деформация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>large-scale effect</kwd><kwd>absolute sizes of samples</kwd><kwd>physicomechanical properties</kwd><kwd>fatigue strength</kwd><kwd>fatigue curve</kwd><kwd>fatigue resistance</kwd><kwd>microstructure</kwd><kwd>sliding strips</kwd><kwd>surface damageability</kwd><kwd>relative deformation</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">Сухонос С.И.
