      <abstract xml:lang="ru">
        <p>Эксплуатация карьерных экскаваторов, оснащаемых зубьями из выеокомарганцовистой стали II0ГIЗЛ, на погрузке взорванных скальных пород показала сравнительно высокую стойкость зубьев (до месяца и более), что объясняет­ся появлением значительного наклепа на их рабочих поверхностях в результа­те сильных ударов при зачерпывании ...</p>

      <abstract xml:lang="en">
        <p>Operation of quarry excavators equipped with teeth of II0GIZL manganese steel on loading blasted rock showed a relatively high resistance of teeth (up to a month and more), which is explained by the emergence of significant riveting on their working surfaces as a result of strong impacts during scooping ...</p>
