Volume is indexed by Thomson Reuters CPCI-S (WoS).This special volume is dedicated to the science and technology of the semi-solid processing of metals. Since the recognition of the possibility of manipulating metals in the semi-solid state, during the seventies, this fascinating technology has experienced dynamic development  and has led to a whole family of new production processes, new equipment and industrial applications. In order to exploit fully the technical and economic potential of these new ideas, it is important to achieve a better understanding of the microstructural development and flow behavior in order to improve material and process modelling as well as process control.
