“…The processing efficiency is high due to the high heat input during high rotation speed FSP (Chen et al, 2017). Liu et al (2020) investigated the microstructure and mechanical properties of FSPed AZ31 alloy with high rotation speed, which shows excellent corrosion resistance and mechanical properties. The dispersion of β-Al 12 Mg 17 precipitates increased with increased processing speed.…”

The nano-ZrO 2-reinforced AZ31 alloy composites were fabricated by friction stir processing with three multi-passes and high rotation speeds. The AZ31/2.14 vol% ZrO 2 , AZ31/4.29 vol% ZrO 2, and AZ31/6.43 vol% ZrO 2 composites were designed. The fine microstructure and uniform dispersion of ZrO 2 particles were observed in the AZ31/ZrO 2 composites. The excellent interfacial bonding was observed between the Mg matrix and ZrO 2. The hardness and tensile properties were enhanced after three cumulative friction stir processing passes. This was attributed to grain refinement and strengthening effects of ZrO 2. The tensile properties and hardness of the AZ31/ZrO 2 composite increased with the increase of volume fraction of the ZrO 2 particles from 2.14 to 6.43 vol%.

“…Magnesium (Mg)-based alloys are widely used in the industries of automotive, aerospace, electronics, transportation, and so on [1][2][3][4][5]. The cause of this is related to low density (i.e., low weight), high shock absorption, high damping, good electromagnetic shielding, high specific strength, and good hot formability [2][3][4]6,7]. On the other hand, the casting of these alloys is cost-effective, and they can be recycled [1,2,7,8].…”

Friction stir welding (FSW) and friction stir processing (FSP) are two of the most widely used solid-state welding techniques for magnesium (Mg) and magnesium alloys. Mg-based alloys are widely used in the railway, aerospace, nuclear, and marine industries, among others. Their primary advantage is their high strength-to-weight ratio and usefulness as a structural material. Due to their properties, it is difficult to weld using traditional gas- or electric-based processes; however, FSW and FSP work very well for Mg and its alloys. Recently, extensive studies have been carried out on FSW and FSP of Mg-based alloys. This paper reviews the context of future areas and existing constraints for FSW/FSP. In addition, in this review article, in connection with the FSW and FSP of Mg alloys, research advancement; the influencing parameters and their influence on weld characteristics; applications; and evolution related to the microstructure, substructure, texture and phase formations as well as mechanical properties were considered. The mechanisms underlying the joining and grain refinement during FSW/FSP of Mg alloys-based alloys are discussed. Moreover, this review paper can provide valuable and vital information regarding the FSW and FSP of these alloys for different sectors of relevant industries.

Thanks to its excellent mechanical properties, magnesium alloys have many potential applications in the aerospace and other fields. However, failure to adequately solve corrosion problems of magnesium alloy becomes one of the factors restricting its wide use in many industrial fields. Inspired by nature, researchers designed and fabricated bio-inspired water-repellent (superhydrophobic and slippery liquid-infused porous surface) surfaces with special wetting properties by exploring the surface microstructures of plants and animals such as lotus leaf and nepenthes pitcher, exhibiting excellent corrosion-resistant performance. This article summarizes the research progress on corrosion resistance of magnesium alloys with bio-inspired water-repellent properties in recent years. It mainly introduces the corrosion reasons, types of corrosion of magnesium alloys, and the preparation of magnesium alloys with bio-inspired water-repellent properties to improve corrosion resistance. In particular, it is widely used and effective to construct water-repellent and anti-corrosion coating on the surface of magnesium alloy by surface treatment. It is hoped that the research in this review can broaden the application range of magnesium alloys and provide a powerful reference for the future research on corrosion resistance of magnesium alloys.
