“…Based on the numerical analysis, they obtained results showing that the Al-SiC composite camshafts have good strain and stress characteristics and can be a good alternative to chilled cast iron and carbon steel camshafts. Sachar et al [21] demonstrated the suitability of aluminum alloys for the construction of cylinder block fins. The low self-weight of this material reduces the weight of the engine and increases its efficiency.…”

The paper investigated the AW7075 aluminum alloy that is used in the automotive industry. The alloy is widely used, among others, in the production of heads and engine blocks. The possibility of obtaining various properties of the alloy (material states) by appropriate heat treatment (saturation and aging) was demonstrated. The results of strength, hardness, abrasion and fracture toughness tests of the alloy in the T73, RRA and HTPP aging treatments, in comparison with the T651 reference state, are presented. The need to select the appropriate parameters of heat treatment in relation to the load conditions of the structural element, especially in elements with notches, was indicated. Depending on the state of the AW7075 alloy, the results prove the wide and diverse possibilities of its use, and should be used consciously in the design and production processes of modern automotive drivetrain components.

“…For example, it was found that the rate of fatigue cracking decreases with decreasing size of precipitates [4]. Trdan et al [21] have also shown that the microstructure of aluminum alloys strongly affects the direction and propagation of a fatigue crack in welded joints.…”
