Effect of input power and interfacial powder size on microwave joining of different materials: A review

Abstract

The use of microwave energy for processing of different materials is gaining significant attention in today's manufacturing industries. The microwave energy found to be applied in sintering, cladding, brazing, joining, casting and drilling of variety of materials. This paper is focused on the detailed review of the research works carried out on the effect of input power of microwave source and interfacial powder size on joint characteristics of different materials. It has been reported that majority of the isotropic to orthotropic materials can be joined using microwave heating source. The characteristics of the joints produced through microwave energy were studied by various researchers using mechano-metallurgical characterization techniques like tensile and hardness tests technique, X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS). The characterization results found in different works are presented in the paper. © 2021 Elsevier Ltd. All rights reserved.
