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

Precipitation Evolution in the Heat‐Affected Zone and Coating Material of AA2024 Processed by Friction Surfacing

Advanced Engineering Materials, Volume 24, Issue 11, November 2022., 2022
Self‐mating coatings from Al–Cu–Mg alloy are generated by friction surfacing. The authors investigate the S/θ‐phase transformations during thermomechanical loading in the substrate and coating using differential scanning calorimetry, transmission electron microscopy, and synchrotron small‐angle X‐ray scattering.

Effect of Friction Stir Welding on the Mechanical and Microstructural Behaviour of AA7075 Aluminium Alloy

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

Assessment of Rotational Speed and Plunge Rate on Lap Shear Strength of FSSW Joints of AA7075/Mild Steel

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
Friction stir spot welding (FSSW) is an upgraded version of the friction stir welding process. This welding process can be used to replace permanent and temporary fastens such as bolts and nuts, screws, rivets, and welds. FSSW can be utilized to replace steel rivets in aircraft structure fabrication due to the elimination of time required to complete ...
