Special Issue Information

Dear Colleagues,

In today's modern industries, the development of new materials is a primary focus in order to meet the requirements of a wide range of demanding applications. Some examples of these applications include marine propulsion systems, vehicle internal combustion engines, and jet turbine engines. Magnesium, aluminium, and titanium alloys are becoming increasingly utilization in aircraft construction due to the discovery of new lightweight metal alloys and composites with ideal mechanical properties, as well as developments in the technologies used to produce lightweight metal. Research on advanced materials and manufacturing methods focuses on fundamental scientific concerns relating to a wide array of innovative materials and the creation of knowledge regarding the use of these materials in a number of applications. The fields of materials engineering and production engineering focus on the application of materials as well as the development, processing, and production of novel materials and methods. Research in these fields will be of assistance in the development of technological products in a variety of domains, such as the production of energy, the automobile and aviation industries, the manufacture of medical equipment, and the transmission of information.

Applications in the automotive and aerospace industries are currently providing novel materials with a substantial amount of attention. Because of the imperative mission to lower vehicle weight, the automotive industry has invested a significant amount of research and development efforts in the discovery of novel materials for the structural components of automobile bodies. In addition, the production of innovative materials results in a number of challenging issues, such as the design of fabricating operations, optimization of process parameters, enrichment of production outcomes, and elimination of manufacturing damages in the preparation of end products.

Therefore, in order to shed light on the most recent advancements in the synthesis and multifunctional applications of innovative materials, the aim of this Special Issue is to publish original and innovative research papers and review articles, which are pertinent to the applications of innovative materials in the automotive and aerospace industries.

Potential topics include, but are not limited to, the following:

  • Recent advancements and challenges of innovative materials and their applications;
  • Additive manufacturing of innovative materials;
  • Nano/micro-fabrication of innovative materials;
  • Structural and chemical characterization of innovative materials;
  • Wear characterization of innovative materials;
  • Machinability studies of metal matrix composites;
  • Thermal and corrosive behaviour of innovative materials;
  • Machinability characterization and evaluation of innovative materials;
  • Innovative materials for aerospace, industrial and biomedical applications.

Due to their excellent mechanical properties and large specific surface area, graphene and its derivatives are widely used in metal matrix composites as reinforcements. In this study, the thermal reduction behavior of large-size graphene oxide are investigated systematically, and reduced graphene oxide (RGO) with few residual oxygen groups and good structural integrity is obtained. ZK61 matrix composites with varying content of in situ RGO are fabricated using the semi-powder metallurgy method. The results reveal that the addition of RGO can cause the refinement of the grains and the second phase, which is attributed to the uniform distribution of the RGO throughout the matrix. The formation of nano-MgO particles is beneficial in increasing the interfacial bonding strength between the RGO and the matrix, resulting in simultaneous increments in yield strength and elongation in the RGO/ZK61 composites. The composite containing 0.6 wt.% RGO shows a superior mechanical property, including microhardness of 79.9 HV, yield strength of 203 MPa and excellent elongation of 17.5%, with increases of 20.9%, 8.6% and 7.4%, respectively, when compared with the ZK61 alloy. Quantitative analysis indicates that the main strengthening mechanisms of RGO-reinforced magnesium matrix composites are load transfer strengthening and grain refinement strengthening. Full article

In this work, we designed ternary ZnSnO3 particle-reinforced Cu matrix composites and evaluated the hot deformation behavior of ZnSnO3/Cu composites. The hot deformation characteristics of typical dynamic recrystallization were probed by the resulting true stress–strain curves of ZnSnO3/Cu composites. The influences of deformation conditions, including temperatures (650–850 °C) and strain rates (0.01–5 s−1), on the flow stress of the designed composites were investigated. This revealed that the peak stress increased with the increasing of strain rate and decreasing of temperature. Additionally, the activation energy was calculated to be 237.05 kJ/mol and followed by yielding a constitutive equation for low-stress ZnSnO3/Cu composites. The processing maps established by dynamic materials model theory indicated that the designed composites possessed excellent hot workability, and then the processing parameters (790–850 °C and 0.01–0.04 s−1) of the ZnSnO3/Cu composites were determined for practical industrial production. Our work discloses the deformation behavior of ZnSnO3/Cu matrix composites and extends the rational process design for ternary ceramic/metal materials with excellent hot workability. Full article
