Ван Чжисинь, Чжоу Цзячэнь, Ма Минсин, Чжао ЛянЧжао

Аннотация


Исследованы пятикомпонентные высокоэнтропийные сплавы AlxCoCuNiTi при x = 0; 0,2; 0,4; 0,6; 0,8; 1,0, выплавленные в вакуумной дуговой печи. Определено влияние содержания алюминия на структуру, фазовый и химический состав сплавов, твердость по Виккерсу и коэффициент трения при испытании на изнашивание. Показано положительное влияние алюминия на структуру и износостойкость сплавов AlxCoCuNiTi.
