The influence of deformation by equal-channel multiple-angle pressing and durable thermal treatment on phase composition and physical properties of NbTi alloy
The influence of deformation by equal-channel multiple-angle pressing and of thermal treatment on phase composition, state of structure and current-carrying capacity of NbTi alloy superconductor have been studied. Deformation is shown to result in the decreasing of subgrain size (100.88200 nm)....

Дослiджено вплив деформацiї рiвноканальним багатокутовим пресуванням та термообробки на фазовий склад, структурний стан i струмонесучу здатнiсть надпровiдника зi сплаву NbTi. Виявлено, що деформацiя спричиняе зменшення розмiрiв субзерен (100...200 нм). Встановлено термостабiльнiсть структури, сформованоi пресуванням у дiапазонi температур До 450 ℃, що пояснюється видiленням дисперсних частинок другої α-фази на межах субзерен. Пiсля деформацiї спостерiгається виразне пiдвищення намагнiчування сплаву внаслiдок закрiплення магнiтного потоку на межах кристалiтiв та видiленнях α-фази. Исследовано влияние деформации равноканальным многоугловым прессованием и термообработки на фазовый состав, структурное состояние и токонесущую способность сверхпроводника из сплава NbTi. Установлено, что деформация приводит к уменьшению размеров субзерен (100.88200 нм). Установлена термостабильность структуры, сформированной прессованием в диапазоне температур до 450 ℃, что объясняется выделением дисперсных частиц второй α-фазы по границам субзерен. После деформации наблюдается отчетливое повышение намагничивания сплава вследствие закрепления магнитного потока на границах кристаллитов и выделениях α-фазы. 2005 Article The influence of deformation by equal-channel multiple-angle pressing and durable thermal treatment on phase composition and physical properties of NbTi alloy / V.N.

The influence of deformation by equal-channel multiple-angle pressing and of thermal treatment on phase composition, state of structure and current-carrying capacity of NbTi alloy superconductor have been studied. Deformation is shown to result in the decreasing of subgrain size (100.88200 nm). In the temperature range to 450 ℃, the used structure was found thermally stable. This is explained by precipitation of disperse particles of the second α-phase at the subgrain boundaries. After the deformation there was a distinct increase in magnetization of the alloy due to magnetic flux fixing at boundaries of crystallites and at α-phase precipitations. |
