Microwave sintering, brazing and melting of metallic materials
… of Metals and Materials Volume 4: New, …, 2006
Microwave energy has been in use for variety of applications for over 50 years. These applications include communication, food processing, wood drying, rubber vulcanization, medical therapy, polymers, etc. In the last two decades microwave heating has been also applied very effectively and efficiently to heat and sinter ceramic materials. Microwave heating is recognized for its various advantages, such as: time and energy saving, very rapid heating rates, considerably reduced processing cycle time and temperature, fine microstructures and improved mechanical properties, better product performance, etc. The most recent application of microwaves has been in the field of metallic materials for sintering, brazing/joining and melting. Several common steel compositions, pure metals and refractory metals have been sintered in microwaves to nearly full density with improved mechanical properties. Many commercial powder-metal components of various alloy compositions including iron and steel, copper, aluminum, nickel, Mo, Co, Ti, W, Sn, etc., and their alloys have also been sintered in microwaves producing better properties than their conventional counterparts by using a 2.45 GHz multimode microwave system. This work has been further extended to join and braze bulk metal pieces, especially super alloy based turbine blades. Further, in a specially designed microwave cavity, even the bulk metals can be made to couple with the microwave field and melted. The implications of these findings are obvious in the field of powder metal technology.

Effects Of Microwave On Molten Metals With Low Melting Temperatures
Journal of Minerals and Materials Characterization and Engineering, 2005
Different metals were tested to determine if microwave irradiation can heat liquid metals. Temperature profiles of different molten metals under microwave radiation revealed that molten metals are primarily microwave reflectors. To explain this phenomenon, microwave heating mechanisms and skin depths of conductors have been introduced. The influences of resistivities on metal skin depths are also discussed.
The casting of materials using microwave energy: A review
Materials Today: Proceedings, 2020
Knowing the advantages of microwave processing on different materials, it has established a good base for the sintering process. Although it has similar advantages for other processes, still other fields are not much established for industrial use. Microwave casting is one of the emerging fields which are yet to be studied in detail. In this paper, a literature review is carried out for the microwave casting of different materials such as metals, metal matrix composites (MCC), etc. Microwave casting is processed under an apparatus that involves microwave hybrid heating (MHH) where heat is transferred to charge using susceptor material. Further depending upon the designed apparatus, microwave casting is divided as in-situ and ex-situ casting processes. If molten material is allowed to solidify inside the microwave cavity is termed as ''in-situ" casting while if molten material is allowed to solidify outside the microwave cavity it is termed as ''ex-situ" casting. From the review, it can be concluded that the microwave casted materials produce better properties as compared to conventional casting processes in terms of homogeneity and mechanical properties. But most of the research is reported for low melting point materials like Aluminum and their alloys. With the implementation of a new design setup, microwave casting can be used for the materials that are having a melting point above 1000°C.

Finite element analysis of microwave heating of solid products
International communications in heat and mass …, 2000
In this paper, the electric field distribution obtained from solving Maxwell's equations was coupled to the energy equation to predict the temperature distribution during microwave heating of solids. The effect of sample rotation was incorporated to the model. Simulation runs showed that rotation of the sample results in a more uniform temperature distribution. In small samples, heating was more pronounced
