A novel process to produce a transition metal alloy thin tube in a dissimilar metal body was examined by modifying the conventional sacrificial-core method. A compound containing titanium powder and a compound with aluminum powder were assembled and shaped into a tube-forming compound wire with concentric layers. An iron powder compact including the tube-forming compound wire was thermally dewaxed and sintered. As a result, a thin tube composed of Ti-Al alloy was directly produced in the iron body.
