Functional heterophasic liquid metals
Responsive Materials, Volume 1, Issue 1, August 2023., 2023 Adding metallic elements in the pure liquid metal (LM) (that forms heterophasic LMs) not only addresses the challenges but also brings appealing features into LMs. The heterophasic LMs broadly expand the applications of LM‐based systems in soft electronics, magnetic robot, catalysis, energy management, and biomedicine. Abstract Liquid metals (LMs) have

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022 In this research work, an attempt was made to weld AA7075 alloy using the friction stir welding (FSW) technique. The experimental runs were designed using the Taguchi L18 orthogonal array and welds were obtained by varying tilt angle, tool rotation speed, tool feed rate, and axial load, whereas weld quality was accessed in terms of tensile strength and

Refill Friction Stir Spot Welding of Similar and Dissimilar Alloys: A Review [PDF]
Acta Metallurgica Sinica (English Letters), 2019 Refill friction stir spot welding, also known as friction spot welding (FSpW), is a solid-state welding process suitable for spot joining of lightweight materials. Through the efforts of improving joint quality for similar and dissimilar materials, for example, aluminum and magnesium, this joining technology is well developed. The joining mechanism and
