Paper Title:
Theory and Technology of Semisolid Metal Molding
  Abstract

Fundamentals of semisolid metal molding, including the particulate feedstock, methods of its generation and features that make it useful for processing, are outlined. Melting characteristics of the feedstock under sole influence of heat are considered, covering a wide range of microstructural and microchemical factors, believed to be of importance at high temperatures. The generation of the thixotropic slurry within the injection molding system and its solidification behaviour are accompanied by detailed features of the molded structures and their correlation with properties of net-shape components. In addition to conventional techniques the novel processing concepts including near-liquidus molding, semisolid extrusion molding as well as the alloy and composite generation in a semisolid state are described. An update on commercialization progress is completed by a characterization of the modern equipment used for process implementation with broad references to metal die casting and plastics injection molding.
