Анотація

Основою функціональної поведінки сплавів NiTi (нітинол) є обернене перетворення між аустенітною та мартенситною фазою, що забезпечує ефект пам’яті форми та надпружність. Температури й кінетика цього перетворення залежать від складу, термічної історії, умов навантаження та мікроструктурного стану матеріалу. У статті проведено огляд сучасних досліджень фазових перетворень у сплавах системи NiTi та їхнього впливу на мікроструктуру і функціональні властивості матеріалу під час лезової обробки.
