Abstract: A process for making a composite integral turbine wheel and the like, consisting of a plurality of blade elements of an airfoil shape connected at their inner ends to the periphery of a sintered rotor or hub and metallurgically bonded thereto. In accordance with the practice of the process, a plurality of identical blade elements in a final machined condition are inserted in a mold at accurate circumferentially-spaced intervals therearound and are disposed such that the inner root sections thereof extend inwardly of a mold cavity defining the rotor profile. The mold cavity is filled with metal powder composed of a high-strength, temperature-resistant alloy, and sintered into a coherent mass in a manner to effect a metallurgical bonding of the sintered rotor section to the individual blade elements.
