It's possible that the machining or stamping processes are causing stress buildup in the material, and the 1400 Deg bonding temp is relieving these stresses, resulting in relaxation and deformation of the material.

You might try broaching (or stamping) the internal spline to near-finish size, then stress relieve the discs (a slow thermal process). Then, finish broaching to size before bonding. This finishing operation will probably improve the spline's surface finish, and should minimize final stresses created by the final machining/stamping. Then bond the facing.
