Special Issue Information

Dear Colleagues,

Aluminum alloys are widely used in various strategic sectors due to their superior properties, such as lightness, strength, corrosion resistance, toughness, electrical and thermal conductivity, recyclability, and formability. These superior mechanical properties make them ideal for critical applications which experience complex operational conditions, as well as adverse environmental actions. However, the need to develop more efficient materials with improved properties requires a deep understanding of the relationships between the microstructural features and the mechanical properties.

The goal of this Special Issue is to provide a comprehensive overview of the more recent advances in the field of mechanical behavior of aluminum alloys, which include alloy design strategies, novel processing techniques, advanced simulation methods, forming and joining technologies, and corrosion protection solutions. Examples of innovative and successful industrial applications, as well as non-conventional experimental or numerical approaches, are also encouraged. Research and review papers addressing all aspects of the mechanical behavior of aluminum alloys are welcome.

The effects of rare earth yttrium (Y) additions and the heat treatment process on the microstructure and mechanical properties of as-cast ADC12 aluminum alloy have been investigated. The results showed that the primary Si crystals were significantly refined from long axis to fibrous or granular when the Y content was 0.2 wt%. Compared to the matrix, the mean area and aspect ratio were decreased by 92% and 75%, respectively. Moreover, the Si and Fe-rich phases were spheroidized and refined with a small average size during the solid solution. It was also noted that the copper-rich phases were dissolved into the matrix. Correspondingly, it was found that after metamorphic and heat treatment the ultimate tensile strength (UTS), elongation, and, hardness increased by 81.9%, 69.7%, and 74.8%, respectively, compared to the matrix. The improved mechanical properties can primarily be attributed to the optimization of the microstructure and the refinement of various phases. Full article

The application fields of friction stir welding technology, such as aerospace and transportation, has high safety requirements and fatigue is the dominant failure mode for weldments. It is of great significance to understand the fatigue properties of friction stir welded joints. This paper provides an overview of the fatigue mechanism, influencing factors, crack growth rate, and fatigue life assessment. It is found that the fatigue performance of friction stir welded joints can be affected by welding process parameters, test environment, stress ratio, residual stress, and weld defect. The optimized process parameters can produce high quality weld and increase the weld fatigue life. Laser peening is an effective post weld treatment to decrease fatigue crack growth rate and improve material fatigue life. Full article
