Однако потенциальные возможности использования таких материалов ограничены, поскольку даже при комнатной температуре сравнительно быстро происходит их охрупчивание (потеря пластичности), которое не может быть восстановлено путем термообработки аморфной фазы. Установлено, что пластичность можно восстановить, применяя термоциклирование в интервале между температурами жидкого азота (77 К) и комнатной (295 К). Этот процесс обработки, получивший название «омоложение» (rejuvenation), оказался приемлемым только для массивных образцов, получаемых в виде стержней. Он непригоден для образцов в виде лент толщиной 20 – 50 мкм (а именно в таком виде получают абсолютное большинство аморфных сплавов). В работе представлена модернизированная методика обработки таких образцов аморфных и частично кристаллических сплавов с помощью криотермоциклирования, позволяющая восстанавливать аморфную структуру и пластичность тонких лент. Рентгенограммы предварительно отожженных при температуре 170 °C ленточных образцов сплава Al87Ni8Gd5 с долей нанокристаллической фазы, не превышающей 10 %, до и после нескольких последовательных циклов «охлаждение – нагрев» показали, что с увеличением количества циклов до двухсот аморфная структура исходного образца может быть полностью восстановлена.</p></abstract><trans-abstract xml:lang="en"><p>Creation of the new technologies includes the development of the materials, among which composite amorphous-nanocrystalline materials, characterized by a unique combination of the magnetic and mechanical properties (high strength, hardness, wear resistance, etc.) hold a specific position. However, their potential application is limited due to the loss of plasticity (embrittlement) which occurs relatively soon even at room temperature and cannot be restored by heat treatment of the amorphous phase. The plasticity can be restored when thermocycling is carried out in a temperature range between the temperature of liquid nitrogen (77 K) and room (295 K) temperature. This process dubbed «rejuvenation» turned out to be acceptable only for bulk samples obtained in the form of rods etc. and appeared to be entirely unsuited for ribbon samples with a thickness of 20 – 50 μm (i.e., the thickness of the absolute majority of amorphous alloys currently obtained). We present a modernized method for processing thin samples of amorphous and partially crystalline alloys using cryogenic thermocycling, which provides restoration of the amorphous structure and ductility of the samples. X-ray diffraction patterns of tape samples of Al87Ni8Gd5 alloy annealed at 170°C with a fraction of the nanocrystalline phase not exceeding 10% before and after several successive cooling-heating cycles show that with an increase in the number of cycles up to two hundred the amorphous structure of the initial sample can be completely restored.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аморфные материалы</kwd><kwd>восстановление структуры</kwd><kwd>кристаллизация</kwd><kwd>термоциклирование</kwd><kwd>криообработка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>amorphous materials</kwd><kwd>structure restoration</kwd><kwd>crystallization</kwd><kwd>thermal cycling</kwd><kwd>cryogenic processing</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">Chunchu V., Markandeyulu G.
