Special Issue Information

Dear Colleagues,

Although modern transport represents a vital part of the global economy, it is also a significant source of pollutants, contributing 13% of overall greenhouse gas and 25% of CO2 emissions coming from the combustion of fossil fuels. The application of materials with high strength-to-weight ratios in transportation vehicles, also known as lightweighting, is an important strategy for improving fuel economy and reducing harmful pollution. Thus, to withstand growing requirements of next-generation vehicles, there is a need for stronger and lighter innovative structural materials.

It is my pleasure to invite you to submit a manuscript to this Special Issue, which will focus on current and emerging structural metallic materials for automotive and aerospace applications. In addition to traditional aluminum-, titanium-, and magnesium-based alloys, this Special Issue will include novel lightweight high-entropy alloys that are also becoming candidates for substantial weight reduction. The scope will cover fundamental research, all aspects of alloy development, synthesis, heat treatment, component manufacturing, the structure–property relationship, testing, computer simulation, and application-related topics.

Submissions of communications, full papers, and reviews are all welcome.

The effect of compound fields of ultrasonic vibration and applied pressure (UV+AP) on three-dimensional (3D) microstructure and tensile properties of recycled Al-Cu-Mn-Fe-Si alloys was systematically studied using conventional two-dimensional (2D) microscopy, synchrotron X-ray tomography, and tensile test. The properties of UV+AP treated alloys with the pouring temperature of 740, 710 and 680 °C were compared when those alloys achieved after gravity casting. After UV+AP treatment, the alloy with pouring temperature of 710 °C show the smallest grain size. Also, the sizes of Fe-rich phases and Al2Cu are greatly reduced and their 3D morphologies are compacted. The mechanical properties of UV+AP treated alloys are relatively higher than those measured for gravity cast equivalents. This improvement can be explained by the synergistic effect of acoustic cavitation, acoustic streaming, and force-feeding, which resulted in the dendrite fragmentation, uniform solute distribution, and microstructural refinement. The Orowan strengthening and solution strengthening were identified as the main strengthening mechanisms. Full article

Title: THERMAL STABILITY OF ALUMINUM ALLOYS: A REVIEW

Abstract:  Aluminum alloys represent an important segment of structural engineering materials with a wide range of industrial applications. A substantial application expansion of Al alloys is hindered by their limited structural stability especially at increased temperatures over extended service time. The ability of retaining the microstructure and properties is additionally affected by reactive environments, heavy/cyclic loads or high-speed applications. Therefore, along with recent re-focusing on strategic importance of Al alloys as lightweight structural materials for transportation vehicles, special pressure is exerted on an improvement of their high temperature capabilities. In this paper, thermal stability as the critical barrier in development of Al alloys is reviewed. Definitions, factors affecting thermal stability and its testing techniques are discussed. Based on strengthening mechanisms in cast and wrought Al alloys, directions in developments of novel grades with improved stability are presented. In the search for new alloys and testing a variety of alloying elements to create thermally stable precipitates, a particular attention is paid to alloying with rare earths and transition metals. Moreover, the role of alloy manufacturing methods, including liquid metal engineering, solidification, post-casting treatments, and wrought processing in property retention, is summarized.
