Thermophysical Properties of Aluminum 1060 Fabricated by Equal Channel Angular Pressing

Abstract: Equal channel angular pressing (ECAP) has the advantage of enabling an ultrafine grain size. Aluminum 1060 is used as a power plant material because of its favorable electrical properties. However, the weak strength of aluminum limits its application. In this study, the thermal conductivity and electrical conductivity of Al 1060 made by ECAP was investigated. ECAP was conducted through the die having a channel angle of 90 • and a corner angle of 20 • at a temperature of 473 K with a strain rate of 2 mm · s −1 … Show more

“…The aluminum/coating interface was an important cooling region because of the extremely high thermal conductivity (~230 W·m −1 ·K −1 [34]) of the aluminum substrate. The region of the molten zone near the aluminum rapidly solidified and formed a hill-like protrusion, as shown in Figure 7a.…”

“…РКУП с углом стыка каналов 90 о за 6 проходов не приводит к образованию однородной по типу структуры, в ней присутствуют дислокационные ячейки, субзерна и зерна, средний размер элементов структуры составляет 0,6-1,1 мкм, что согласуется с данными работ [11][12]. То есть 6 проходов при РКУП с традиционным углом деформирования недостаточно, чтобы получить равноосную однородную ультрамелкозернистую структуру.…”

“…Проведенные в работе [10] исследования напряженно-деформированного состояния и энергосиловых параметров, проведенные на основе компьютерного моделирования в программном комплексе DEFORM процесса деформирования заготовок в равноканальных угловых матрицах новой конструкции, позволили сделать вывод, что 2-й вариант РКУ матрицы с углом стыка каналов 45 0 (рис. 1, б) является наиболее удачным.…”

“…The thermal conductivity of Al1060 was measured by Lee et al [29], whose fitting equation was used for this model. The IL was assumed to be UAl 3.5 considering most ILs observed are composed of UAl 3 and UAl 4 .…”
