Металеві багатокомпонентні високоентропійні стопи (ВЕС) являють собою новий клас матеріялів, що наразі активно вивчаються. У статті проаналізовано еволюцію досліджень в галузі ВЕС, розглянуто потенційні напрями застосування подібних матеріялів. Розглянуто сучасні дослідження ВЕС, зокрема вплив різних елементів на властивості ВЕС з різною основою, формування мікроструктури таких матеріялів і дослідження в галузі проєктування. Результати аналізи показали, що у більшості випадків для виготовлення ВЕС використовуються порошки чистих металів, а для одержання ВЕС використовуються достатньо складні технології, наприклад плазмове спікання, магнетронне розпорошення. Для пониження вартости ВЕС порівняно з традиційними матеріялами все більш популярним напрямом стає створення так званих квазивисокоентропійних стопів (КВЕС). Загальний принцип створення КВЕС такий же, як і ВЕС: використовується багатокомпонентна система, що складається щонайменше з 5 компонентів, проте еквіатомова концентрація дотримується нестрого, а під час виробництва КВЕС вимоги до шихти та способу витоплення значно нижчі. Це уможливлює підвищення комерційної привабливости КВЕС за рівня властивостей, які можна порівняти з властивостями ВЕС.

Ключові слова: високоентропійний стоп, квазивисокоентропійний стоп, еквіатомова концентрація, феростопи, собівартість.
