  • Continuous severe plastic deformation process for metallic materials
    Patent number: 6895795
    Abstract: A method of processing a billet of metallic material in a continuous manner to produce severe plastic deformation. The billet is moved through a series of CSPD dies in one operation to efficiently produce a billet characterized by a controlled grain structure. The long billets of metal stock are moved along the processing path through the CSPD dies with plural sets of pinch rolls which grip the billet and push it into the entry channel of the dies. Other sets of pinch rolls pull the billet from the exit channel of the dies.
