of the viscous medium and aluminum particles, the aluminum particles can settle in the viscous medium during the forming process. The settling velocity is related to the size of the particles, as well... efficiency. 5 Conclusions 1) The settling velocity of the aluminum particles in the viscous medium is related to the particle size and forming temperature. When the particle size is larger than 3 mm......
), Bhopal-462007, India Received 23 April 2010; accepted 26 September 2010 Abstract: Electromagnetic forming (EMF) is a high velocity forming process that uses impulse magnetic force. Coil is an important... (EMF) is a high velocity forming process, which utilizes pulsed magnetic force to deform metallic workpiece. Some of the major advantages of this process are reduction in wrinkling and spring back[1......
