This book discusses the development of spot welding electrode and its fabrication using Cu-WC through a powder metallurgy route. This book consists of dispersed strengthening material and its strengthening mechanisms; studies on spot welding performance of copper-tungsten carbide composite and RWMA class II Cu-Cr electrodes; several methods used for production of MMC reinforced with particulate; the densification behavior of dispersion strengthening copper composite reinforced with high-grade tungsten carbide during cold pressing and sintering; and the sensification and characterization of nanostructured Cu-NbC composite synthesized by in-situ reaction of niobium and graphite powders.
