Electromagnetic Field Assisted Metallic Materials Processing: A Review

Abstract

Electromagnetic fields have been widely applied in the field of materials processing, preparation, and analysis. The effectiveness during such processing is, however, highly dependent on the physics of the applied electromagnetic field as well as the electromagnetic responses from the materials. In order to improve the efficiency of electromagnetic field processing, understanding the fundamentals as well as the engineering of the corresponding electromagnetic effects is crucial. Focusing on metallic materials, this research gives a critical overview and discussion on different electromagnetic effects. Subsequently, the electromagnetic responses in different electromagnetic technologies are further discussed. Specifically, the industrial application potential for inclusion removal from liquid metals is evaluated and the energy coefficient is noticed to be substantially improved by increasing the magnetic flux density.

Solidification Processing of Metallic Materials in Static Magnetic Field: A Review

“…As mentioned above, there have been excellent reviews regarding solidification processing of metallic materials, as referred to in the literature [5][6][7][8]10,12,13,26]. The objective of this section is to summarize the research findings in recent years.…”

“…In past decades, the emergence of effective strategies using external fields, such as magnetic field, electric field and ultrasonic field, has become a potential trend in the field of metal solidification processes, which can effectively regulate nucleation and growth and further modify solidification structures [6,7]. Owing to contactless interaction and various magnetic effects, the application of the magnetic field to solidification processing has attracted intensive attention [8][9][10][11][12][13]. The magnetic field is implemented in two types, i.e., the time-varying and static magnetic fields.…”
