Preparation of Hafnium Bars Manufacture

Abstract: Определены условия, позволяющие при различных переделах сохранять в металле низкое содержание примесей. Сделан анализ процессов формирования структуры в металле в зависимости от режимов деформационнотермической обработки полуфабрикатов и их влияния на свойства готовой продукции. Для получения исходных слитков использовали электронно-лучевую плавку. Деформационную обработку слитков проводили с использованием ковки и прокатки в профильных валках. Конечную термообработку совмещали с выравниванием прутков. Поверхн… Show more

“…Also, hafnium has a high affinity to the interstitial elements (oxygen, nitrogen, carbon, and hydrogen) which can lead to the formation of undesirable oxide, nitride, carbide, and hydride compounds in the near-surface layer of hafnium [10 -14]. In addition, a near-surface layer of hafnium can be enriched with chromium and iron, which are the main components of the steel rolling rolls [15,16].…”
