Special Issue Information

Dear Colleagues,

Adopting light-weight equipment and reducing the quantity of materials used are new and essential trends in science and technology. Adopted to preserve our limited stores of natural resources and energy, these metals and alloys are materials of relatively low density and high strength-to-weight ratios, e.g., lithium (Li), beryllium (Be), aluminum (Al), magnesium (Mg), titanium (Ti), and so on. Light-weight metal and alloys are widely used in aerospace, automotive, architectural, lithographic, packaging, and electrical applications. For example, about 70% of commercial civil aircraft airframes are made from aluminium alloys and, without aluminium, civil aviation would not be economically viable. Saving even one kilogram of metal in the design and construction of an aircraft can result in important weight reductions, lowering construction costs and fuel requirements. Beryllium is used in aircraft components, missiles, spacecraft, satellite gyroscopes, scan mirrors, sports equipment, and electronics as a structural and functional material. This metal offers the beneficial attributes of high flexural rigidity, thermal stability, thermal conductivity and low density. The development of high-performance light-weight metals and alloys is increasing in pace and scale. Materials with high performance, stability, and low cost are critical for realizing a sustainable future.

The aim of this Special Issue, entitled “Advanced Light Metal and Alloys: Preparation, Characterization, and Applications”, is to present recent advancements in various aspects related to material design, processes and applications. Potential topics include, but are not limited to:

The development of advanced light-weight metals and alloys with high strength, high temperature resistance, corrosion resistance, and other excellent properties;

  • The design of high-performance light-weight metals and alloys using empirical, theoretical and computational methods, including DFT, deep learning, etc.;
  • The development of new process methods and heat treatment methods of light-weight metals and alloys including friction stir processing (FSP), additive manufacturing (AM), and related topics;
  • Microstructural evolution and related mechanism exploration in light-weight metals and alloys subjected to deformation, corrosion, creep and other processes.

We are pleased to invite you to submit full research papers, communications, and review papers to this Special Issue.

Abstract
Al 6082 aluminum alloy has excellent corrosion resistance, strength, and formability. However, owing to the recrystallization effect of a hot working process, coarse grains form easily in this material, which reduces its strength and service life.

Al 6082 aluminum alloy has excellent corrosion resistance, strength, and formability. However, owing to the recrystallization effect of a hot working process, coarse grains form easily in this material, which reduces its strength and service life. The novel continuous casting direct rolling (CCDR) method can prevent the deterioration of this material. Thus, we used CCDR Al 6082 aluminum alloy as the research material in this study. By subjecting a CCDR Al 6082 aluminum alloy to heat treatment (T4 and T6) and cold rolling, the influence of recrystallization effect on its mechanical properties and on impact failure resistance were explored. The results demonstrated that the specimen subjected to T4 heat treatment had a higher elongation and that the specimen subjected to T6 heat treatment had a higher strength. After cold rolling, the hardness and strength of the specimens subjected to different heat treatments (coded T4R4 and T6R4) increased because of the work’s hardening effect. Moreover, the elongations of both specimens decreased, but they were higher than the industrial standard (>10%). The strength of specimen T6R4 was higher (up to 400 MPa) than specimen T4R4. Moreover, relative to specimen T4R4, specimen T6R4 had greater tensile and Charpy impact failure toughness. Full article
