【Abstract】 Presents the asynchronous rolling and extrusion process by which, the soldifying dendritic microstructures are subject to shear deformation to achieve the formation of non dendritic microstructures achievable by bending, separating and fragmenting while the requirements for semi solid stocks required for manufacturing large products are satisfied by combining this process with integration and pressure welding technology.更多还原
