“…These materials are highly valued for the combination of such characteristics as high strength-to-weight ratio, high conductivity, corrosion resistance, technological ductility, thermal stability, etc. [1][2][3][4][5][6][7][8][9]. Further enhancement of properties of aluminum alloys is an important area of modern materials science.…”

The data on the study of mechanical properties of cylindrical specimens of Al alloy 6101 in different states under static tension at room temperature are presented. The specimens were tested after natural aging, artificial aging, and ECAP. The surface of fractures of these specimens was also investigated using an electron microscope, and a chemical analysis of elements on the surface of fractures was carried out. Basing on the performed study, it can be concluded that alloy 6101 shows the highest strength (ultimate tensile strength 350 MPa) after ECAP treatment in UFG state. It was confirmed due to the chemical analysis that destruction pores in this material originate on particles of secondary phases based on impurity iron.

“…The aim of this research is to study the destruction features of alloy 6101 of Al-Mg-Si system in various states -after natural aging, artificial aging and ECAP. The destruction nature of alloys of this system, processed by ECAP method, has previously been studied only in a few works, for example [6,7,11].…”

Проблема расчета прочности и долговечности различных конструкций из металлов является одной из важнейших в современном мире. Для ее решения необходимо понимание определенных механических критериев материала, таких как прочность, пластичность и др. [1, 2]. В данной работе приводятся данные расчета и указан характер распределения критических напряжений, которые определяют зарождение пор внутри материала, в данном случае в Al-6101, при статическом нагружении. Зарождение и слияние пор представляют собой первую стадию разрушения материала. При наличии данных о критических напряжениях материала можно спрогнозировать его дальнейшее разрушение [3, 4]. Calculation of strength and durability of various metal structures presents one of the most significant tasks in the contemporary world. To achieve it, the different mechanical criteria of the material, such as strength, ductility, etc. [1, 2] should be known. The calculation data and t distribution pattern of critical stresses that define formation of pores in the material (in our case, Al-6101) under static loading are presented in this article. The first phase of material fracture is the pore formation and merging. Therefore, its subsequent fracture can be estimated using the data on the critical stresses of the material [3, 4].
