Равноканальное угловое прессование (РКУП) стало эффективным методом интенсивной пластической деформации для производства сверхмелкозернистых металлов с улучшенными механическими свойствами, такими как хорошее сочетание прочности и пластичности. Сведения о влиянии маршрутов РКУП на механическую прочность и микроструктуру алюминиевого сплава 5052 от­сутствуют. В данной работе для обработки сплава Al – Mg (5052) использовалось несколько маршрутов деформации, а именно A, Ba, Bc, и C. Маршрут деформации A включал в себя многократное проталкивание образца в матрицу РКУП без вращения, маршрут Ba предполагал поворот образца на 90° в разных направлениях между проходами, маршрут Bc – поворот образца на 90° в одном направлении между проходами, а маршрут C – поворот образца на 180° между проходами. Добавление количества проходов уменьшает размер зерна образцов, обработанных РКУП, по сравнению с образцом после отжига. Исследование микроструктуры показало, что образцы после восьми проходов имеют более мелкий размер зерен, чем после отжига. Маршрут Bc зарекомендовал себя как наиболее эффективный для получения равноосной ультрамелкозернистой структуры по сравнению с другими маршрутами деформации. Это явление происходит из-за непрерывной деформации во всех кубических плоскостях и восстановление после четвертого прохода будет формировать быструю эволюцию субзерен к большеугловым границам зерен, образуя равноосные зерна. Добавление числа проходов РКУП увеличивает твердость алюминиевого сплава 5052. Образцы, обработанные по маршруту Bc, показывают самую высокую твердость – 168,4 HB. Более того, подобное явление обнаруживается, когда предел прочности при растяжении всех путей деформации РКУП имеет сопоставимые значения. Влияние термической обработки образцов с маршрутом Bc также показывает, что отожженный при 200 °C образец имеет самый высокий показатель твердости и предел прочности на растяжение по сравнению с другими образцами.

Equal-Channel Angular Pressing (ECAP) has become an effective technique of severe plastic deformation designed to produce ultrafine grain metals with improved mechanical properties, such as a good combination of strength and ductility. A  report on the effect of ECAP routes on the mechanical and microstructure of commercial 5052 aluminum alloy needs also to be included. This work has been undertaken, in order to obtain the results. In this work, several deformation routes were used to process the Al – Mg (5052) alloy, namely A, Ba, Bc and C. Deformation route A involved repeatedly pushing the sample into the ECAP die without rotation, route Ba was performed by rotating the sample through 90° in alternate directions between each pass, route Bc by rotating the sample 90° in the same sense between each pass and route C by rotating the sample 180° between passes. The addition of the pass number decreases the grain size of ECAP-processed samples when compared to the as-annealed sample. It also confirmed that the microstructure of the 8-pass samples shows a finer grain size than the as-annealed sample. Furthermore, the Bc route (samples rotated in the same sense by 90° between each pass) has been proven to be the most effective deformation route, in order to obtain equiaxed ultrafine grain structure when compared to other deformation routes. This phenomenon takes place due to the continuous deformation in all cubic planes. The restoration after the 4-pass number will lead to the rapid evolution of sub-grains to high-angle grain boundaries, forming equiaxed grains. The characterization of the hardness number also shows that the addition of the ECAP pass number increases the hardness number of 5052 aluminum alloy, where samples processed with the Bc route indicate the highest hardness number at 168.4 HB. Moreover, a similar phenomenon also suggests that the tensile strength of all ECAP deformation routes has comparable values. The effect of heat treatment for samples with the Bc route also shows that 200 °C annealed samples have the highest hardness number and tensile strength when compared to other samples.
