Abstract
A blade member is oscillated in the direction of arrow A-A relative to a rim of a disc; a forge force is applied radially and a weld is formed along line; the blade member is formed from a face centred cubic (FCC) nickel based single crystal alloy, such as CMSX-4 of Cannon-Muskegon Corporation; the orientation of the single crystal blade member is controlled to maximize the stress on the slip plane; by maximizing the stress on the slip plane the in-plane friction forces and the forge force are minimized; minimizing the in-plane forces enables the single crystal blade member to be successfully welded to the rim of the disc.
