Abstract : This report covers research activities in the broad area of deformation of solid metals and include work on metal refining, metal strengthening, and rheological behavior. A new process for metal refining is described that combines squeezing the liquid from semi-solid metal with heating of the semi-solid mass. Another new process is described for strengthening metals by squeezing out small quantities of interdendritic material. Fundamental rheological work on the behavior of semi-solid alloys is also described. (Author)
