“…Takatori et al [1] and Shimizu et al [25] concluded that one body forming of the large radial wheel was not practical using the current injection molding method. Therefore, the processes of fabrication of radial wheel were attempted dividing the hub of the wheel (the thickest section) in two axially symmetrical parts to reduce the thickness about in half [87]. The resulting parts were injection molded separately and the survival probability of the wheel after binder removal step increased markedly.…”

Silicon nitride (Si3N4) radial inflow turbine wheels were fabricated by injection molding at Toyota Central R & D Labs. The wheel was 142mm in outer diameter and had 14 blades. The radial wheel was too bulky to manufacture as a homogeneous and defect-free body in one piece. It was divided into two pieces for injection molding and put together into one body by a cold isostatic pressing step after binder removal. Spin testing was executed at room temperature and the resulting photographs taken from three directions provided useful information about the fracture mode of the wheels. The maximum burst speed of the wheels at room temperature was 98,900 rpm, which corresponded to 145% of the design speed. In a hot rig test, one of the wheels survived 75,000rpm for ten minutes at a turbine inlet temperature of 1,050°C.
