Abstract : A state-of-the-art survey of precision forming methods used to fabricate smal turbine wheelsAND GEARS WAS MADE. The areas of precision forming capabilities, turbine wheel and gear application, and high temperature alloy development were reviewed in terms of a precision forging development program. Of the limited processes utilized to fabricate small turbine wheels with integral blades and high speed gears, the radial extrusion method is recommended. An axial flow, impulse type turbine wheel and a high speed spur gear are recommended for forming process development. The AISI 9310 carburizing grade steel was selected for the initial forging trials and a Nibase alloy, such as Waspaloy, will be utilized for turbine wheel forging developments. (Author)
