Special Issue Information

Dear Colleagues,

Owing to the amazing combination of light weight, high specific strength, excellent corrosion resistance and exceptional recyclability, non-ferrous aluminum-based metallic materials enjoy the leading position in load-bearing applications in industries including automobile and aerospace. In the efforts to meet the incessant demand for increasing the strength of aluminum in order to serve the ever-developing technology, one of the earliest milestones was set by the discovery of the age-hardening phenomenon in aluminum alloys in 1901 by Alfred Wilm. The strengthening of metallic materials is usually accomplished by controlling microstructural defects to obstruct dislocation motion under applied stress. Accordingly, in the last century we have seen breakthroughs in the creation of stronger aluminum through mechanisms of solid-solution strengthening, precipitation hardening, grain-boundary strengthening and work-hardening strengthening.

In recent years, high-strength aluminum alloys with substantial ductility have been developed by the creation of ultrafine grain or nano-crystalline microstructure (nanostructured) and by the dispersion of extremely fine harder reinforcement particles (nanocomposites). These nanostructured metallic materials were processed thermo-mechanical process, while the nanocomposite metallic materials were processed using traditional ingot metallurgy and powder metallurgy processes.

This Special Issue of Nanomaterials will attempt to cover the most recent advances in aluminum-based nanocomposites and nanostructured materials, from design, synthesis and characterization to their applications. 

Potential topics include, but are not limited to:

  • Fabrication and characterization of nanoparticles-reinforced aluminum composites;
  • Fabrication and characterization nanostructured aluminum;
  • Effect of fabrication method on the properties of nanostructured and nanoparticles-reinforced aluminum;
  • Effect of alloying on the properties of nanostructured and nanoparticles-reinforced aluminum;
  • Plasticity of nanostructured and nano-particles reinforced aluminum
  • Application of nanostructured and nanoparticles reinforced aluminum;
  • Additive manufacturing of nanostructured and nanoparticles reinforced aluminum;
  • Wear and degradation behavior of nanostructured and nanoparticles-reinforced aluminum.

6061 aluminum composites with 0.5 and 1 vol. % graphene nanoplatelets as well as 1 and 2 vol. % activated nanocarbon were manufactured by a powder metallurgy method. Scanning electron microscopy and Raman spectroscopy were used to study the morphology, structure, and distribution of nanocarbon reinforcements in the composite samples. Density Functional Theory (DFT) calculations were performed to understand the aluminum-carbon bonding and the effects of hybridized networks of carbon atoms on nanocarbon aluminum matrix composites. Scanning electron microscopy showed the good distribution and low agglomeration tendencies of nanoparticles in the composites. The formation of secondary phases at the materials interface was not detected in the hot-pressed composites. Raman spectroscopy showed structural changes in the reinforced composites after the manufacturing process. The results from Density Functional Theory calculations suggest that it is thermodynamically possible to form carbon rings in the aluminum matrix, which may be responsible for the improved mechanical strength. Our results also suggest that these carbon networks are graphene-like, which also agrees with the Raman spectroscopy data. Micro-Vickers hardness and compressive tests were used to determine the mechanical properties of the samples. Composites presented enhanced hardness, yield and ultimate strength compared to the 6061 aluminum alloy with no nanocarbon reinforcement. Ductility was also affected, as shown by the reduction in elongation and by the number of dimples in the fractured surfaces of the materials. Full article

Creating alloys with a gradient microstructure in grain size has been shown to be a potential method to resolve the trade-off dilemma between strength and ductility. However, different textures developed with various processing methods cannot be fully eliminated, which can significantly affect the mechanical behavior of alloys. In this study, we use a multiscale framework based on dislocation theory to investigate how the combination of rolling texture and gradient in grain size affects the plastic deformation of nano-gradient aluminum during a tensile test. We found that specific rolling textures, such as {110} texture, can significantly enhance the strength and ductility of nano-gradient aluminum. This improvement is the result of the grain being reoriented and the redistribution of stress and strain, which are caused by the combined influence of texture and variation in grain size. These results provide new insights into developing high-performance aluminum by mediating texture and grain size gradient. Full article
