Abstract
Semi-solid processing involves forming metallic alloys between the solidus and the liquidus. The microstructure must consist of solid spheroids in the liquid matrix, rather than dendrites, for the process to operate. The material then behaves thixotropically i.e. it flows when it is sheared but thickens again when allowed to stand. The behaviour was first discovered by Flemings and coworkers in the 1970s and is utilized in a family of processes, some now applied commercially. Here the current status of semi-solid processing, both technologically and from a research point of view, will be reviewed.
