Book excerpt: The title presents an up-to-date account of the research, development, and applications of metallic alloys, recent research into the structure of charge materials, melt treatment, and casting technologies, and their influence on the properties of melts and ingots. This research has confirmed theoretical concepts about the microheterogenous constitution of metallic melts and has made it possible to manage the quality of castings and ingots of various alloys by their special treatment in the liquid state. The four chapters of the book give theoretical and experimental evidence of the effect of the melt constitution on the structure and properties of the solid metal. Liquid Metal Processing: Applications to Aluminium Alloy Production considers common features of structure formation in aluminium alloys for a wide range of solidification conditions, including ultrasonic and thermal melt treatments and discusses the technological problems of these treatments.
