“…These structures are characterized by increased strength and at the same time they have low weight and high resistance to various loading levels. The cellular structures are manufactured using mainly the mechanical and electrochemical processing technologies [5][6][7][8][9]. Concerning the manufacturing of these structures, slow deformation at high temperatures with excess gas pressure is one of the most promising technologies.…”

Multi-layer cellular workpieces are used to manufacture fuel tanks, as well as the external hulls of aircraft. These designs are characterized by low weight and high strength. Monotonic formation with inert gases looks promising for the manufacturing of large workpieces. This article presents an approach to the modeling of energy-force parameters during free forming of titanium alloy workpieces in square dies with shortterm creep. The results of mathematical modeling of the investigated process are given in the form of inequations which allow estimating pressure and critical modes. According to these inequations, we found the influence of the process time on blank's relative thickness change in various points of its surface, as well as on its height and maximum damage rate change.

“…В последние десятилетия в связи с ростом стоимости легирующих элементов все больший интерес вызывают комбинированные термоде-формационные обработки, которые позволяют в низколегированных конструкционных ста-лях получать значения прочности, характерные для средне-и высоколегированных сталей. Су-ществует ряд работ по исследованию комби-нированных технологий, включающих в себя наноструктурирование методом РКУП с по-следующим деформированием сжатием (ковка, штамповка) для пластичных материалов, таких как алюминиевые и магниевые сплавы [1][2][3][4][5][6]. В настоящей работе исследованы структура и ме-ханические свойства конструкционной стали 09Г2С после комбинированной мегапластиче-ской деформации, состоящей из равноканально-го углового прессования (РКУП) и всесторонней ковки (ВК).…”

“…Furthermore, Kim et al 5 also completed a study on the isothermal forgeability of AA6061. In the research work from Puertas et al, 6 the study of an isothermal forging between plane-shape dies is carried out in the case of an AA5083 aluminium alloy, previously processed by ECAP at room temperature. One of the most significant conclusions of this research work is that the ECAP process improves the forgeability of this type of alloy and also that after the isothermal forging, the microstructure continues to be submicrometric.…”

In this research study, a comparative examination on the mechanical properties of AA6063 has been carried out after having been processed by isothermal forging, using plane-shape dies and starting from different initial deformation states. It introduces the novelty of employing experimental data obtained from the isothermal forging so as to model the flow rules of AA6063 processed by equal channel angular pressing taking temperature into account and using artificial neural networks to this end. Subsequently, these flow rules are employed to model the behaviour of AA6063 by means of finite element simulation. Furthermore, a validation of the experimental results is made with those obtained from the simulations using the flow rules attained with the neural networks. It is shown that it is possible to achieve higher precision than with traditional fitting methods of flow rules. In addition, this study presents the novelty of carrying out a comparative study between different starting material states, prior to forging, including among these material previously processed by the severe plastic deformation process, which is referred to as equal channel angular pressing. Moreover, the experimental results obtained when processing the aluminium alloy by equal channel angular pressing are compared to those states, which correspond to the traditional way of working on aluminium alloys, which can be quenched and aged for the purpose of improving their mechanical properties.
