Synthesis of Metallic Materials by Arc Melting Technique

Arc melting technique, which is widely used for preparation of alloys, intermetallics, and metal-based composites, is discussed in this chapter. Basic principle of electrical arc generation and its utilization for melting of materials has been outlined. Design and operation of laboratory-scale arc melting furnace as well as melt-casting furnace have been presented. Operational principle of graphite arc furnace and consumable electrode-based industrial arc furnace is also mentioned. Advantages and limitations of arc melting technique are summarized with few examples towards the conclusion. Contents of this chapter would be useful to students and researchers engaged in development of metallic materials.
