A composite engine component comprises a body having an outer circumferential surface and an inner circumferential surface. The body of the engine component is of unitary, integral, one-piece construction and comprises a radially inner section and a radially outer section having different material compositions. The radially inner section and the radially outer section of the body are welded together using a magnetic pulse welding process in which a metallurgical bond is formed along a bonding interface between the inner and outer sections of the body.
