Special Issue Information

Dear Colleagues,

Magnesium alloys have garnered increasing recognition as the lightest structural metal, boasting impressive characteristics such as remarkable specific strength, castability, formability at high temperatures and damping capacity. These outstanding attributes position magnesium as a promising choice for a wide range of engineering applications. On the other hand, several properties such as strength at high temperatures and corrosion resistance have remained inferior to its counterparts. Consequently, numerous attempts have been made already to enhance these properties. Nevertheless, there is a continuing need to comprehend the connections between microstructure and mechanical-corrosion properties in different alloys. This understanding is crucial for the advancement of next-generation magnesium alloys with superior performance.

This Special Issue has the clear objective of establishing an inclusive forum for materials scientists and engineers to exchange and distribute the latest research breakthroughs concerning the properties of magnesium alloys. The potential subjects covered in this Special Issue are microstructure evolution, new alloy development, heat treatment, plastic deformation, mechanical properties, surface treatment, corrosion and corrosion protection. It warmly welcomes original research and review articles.

The sheet metal forming of magnesium is challenging due to the material’s complex springback behaviour, which is due to the tension/compression yield mismatch. In this study, three different AZ31 grain sizes are produced by a special heat treatment, while maintaining the material strength in uniaxial tension at a similar level. Pure, V-die and channel bending tests are combined with roll forming to compare bending scenarios with and without tension applied transverse and parallel to the bending axis. This is complemented with electron backscatter diffraction to measure the twinning type and twinning area fraction (TAF) in the tension and compression bending zones. Our study shows that, like conventional steel, when bending magnesium, springback reduces with the increasing level of the outer fibre bending strain, i.e., when the bend radius is decreased and the TAF increased. It is further shown that when tension is applied, the TAF increases. However, while in some forming cases, the increase in TAF leads to a clear reduction in springback, in other forming cases the effect of the TAF on springback is less pronounced. Overall, this study provides clear evidence that the twinning behaviour in bending magnesium is influenced by the bend deformation mode and that this influences the springback behaviour. Full article

The long-period stacking ordered (LPSO) structure, functioning as a strengthening phase in magnesium alloys, plays a pivotal role in compensating for inherent performance limitations. In this study, an as-cast Mg-Gd-Ni-Y alloy, including the LPSO phase, was initially obtained through an ingot metallurgy process. Subsequently, the alloy underwent distinct thermal treatments: annealing at 500 °C for 10 h, and extrusion using an extrusion ratio of 10 at a speed of 5 mm/s. Comparative analysis of the microstructure and corrosion characteristics was performed across these three alloy states. Comprising primarily of α-Mg, LPSO phase, and eutectic structures (ES), the alloy exhibited distinctive microstructural features. Immersion experiments conducted in a 3.5% NaCl solution revealed that the as-cast alloy displayed the highest dissolution rate at various temperatures, from room temperature, to 50 °C, and 70 °C. Following annealing, a reduction in the second phase content within the alloy significantly contributed to the observed decrease in its dissolution rate. Extrusion processes resulted in a denser network structure within the microarchitecture, to some extent impeding the spread of corrosion to some extent. By emloying scanning Kelvin probe force microscopy (SKPFM) and micro-electrochemical testing, it was discerned that predominantly the electrochemical system involving α-Mg and the second phases predominantly dictated the heightened dissolution rate of the alloy. This study presents valuable insights into understanding the dissolution mechanisms and potential strategies for controlling the dissolution performance of magnesium alloys containing the LPSO phase.

In this study, indium was added to the binary Mg-Zn alloy to prepare an ultrafine-grained ternary Mg-Zn-In alloy with enhanced mechanical and corrosion properties. The bulk Mg-Zn-In alloy was synthesized through a combination of mechanical alloying and powder metallurgy techniques. The SPEX 8000 mixer mill was used to carry out the process under an argon atmosphere. The mixed powders were mechanically alloyed for 24 h. The mixture was uniaxially pressed at a compacting pressure of 600 MPa. The green compacts were sintered under a protective argon atmosphere at 300 °C for 1 h. The evolution of the microstructural, mechanical, and corrosion properties of Mg-based alloys was studied. X-ray diffraction and scanning electron microscopy were used to analyze the phase and microstructure. The changes in hardness and corrosion properties were also measured. Compared to binary Mg-Zn alloy samples modified with In, the samples exhibited a higher microhardness, which can be related to structure refinement and phase distribution. Based on the results of electrochemical testing, it was observed that the modified samples exhibited an improved level of corrosion resistance compared to the Mg-Zn binary alloy. Full article

It is well known that the poor corrosion resistance of magnesium alloys is a key factor limiting their application. Field exposure is the most reliable means to evaluate the atmospheric corrosion performance of magnesium alloys. This article reviews the field exposure corrosion behavior of magnesium alloys in typical atmospheric environments (including the marine atmosphere, industrial atmosphere, etc.) in recent years. According to the literature review, it was found that there are significant regional differences in the atmospheric corrosion behavior of magnesium alloys, which is the result of the coupling of multiple factors in the atmospheric environment. By investigating the corrosion rate and corrosion products of different types of magnesium alloys in different environments, the corrosion mechanism of magnesium alloys in different environments was summarized. Specifically, environmental parameters such as atmospheric temperature, relative humidity, CO2, and chloride ion deposition rates in the marine atmospheric environment can affect the corrosion behavior of magnesium alloys. The corrosion of magnesium alloys in different industrial atmospheric environments is mainly affected by atmospheric temperature and relative humidity, as well as atmospheric pollutants (such as SO2, CO2, NO2) and dust. This review provides assistance to the development of new corrosion-resistant magnesium alloys. Full article
