Abstract: A rotor disc for a rotor shaft member of an axial flow turbine apparatus is disclosed. The disc has disposed externally thereon a flat surface which lies parallel to a predetermined longitudinal plane extending within the disc. The plane is disposed within the disc so as to extend through a keyway utilized to prevent rotation of the disc relative to the shaft. The predetermined longitudinal plane within the disc is the plane in which cracking of the disc is most likely to occur. The externally disposed, flat, surface area of the disc permits an ultrasonic signal emitted from a transducer disposed adjacent to the external surface to propagate in a direction substantially perpendicular to the predetermined plane within the disc.
