“…The influence of the processing mode of aluminum alloy 01420 on the probability distribution curves of cyclic durability: 1, 3 -mechanical-thermal treatment, 2, 4, 5 -hardening. Symmetrical cantilever bending with a frequency of 25 Hz at σа=100MPa in air (3,4,5) and in a corrosive environment (1,2).…”

“…Under operating conditions, automobile parts, in most cases, experience significant vibration loads. 4 However, when choosing technological equipment, they are often guided by any criteria (for example, manufacturability, efficiency of the shaping process, etc.) except for the ability of stamped products to resist the effects of cyclic loads, since information on the resistance of aluminum alloys deformed to different levels of fatigue fracture air are very limited, and in a corrosive environment are practically absent.…”

The idea of reducing the mass of cars through the use of lightweight materials is not new. Among them are aluminum alloys, which at a relatively affordable price are significantly lighter than steel alloys. The decrease in the vehicle's own mass leads to an increase in their fuel economy, reduction in the amount of harmful substances and compounds released into the atmosphere, and plays an important role in reducing the "greenhouse effect". Structural materials in the manufacturing process of car parts are subjected to various technological treatments, including plastic deformation operations. Vehicle operation is associated with significant vibration loads. However, information on the influence of the mode of technology for manufacturing parts from aluminum alloys on the resistance to fatigue failure in air is limited, and in a corrosive environment it is practically absent. The paper considers the possibility of using lightweight high-strength aluminum alloys in the automotive industry, taking into account the increase in their operational reliability by optimizing the manufacturing technology of parts. The results of the study of the influence of the degree and rate of plastic deformation during technological processing on the kinetics of fatigue fracture and the operational properties of some aluminum alloys are presented.
