Abstract
A method for forming a turbine or compressor wheel from a semi-solid material uses a die assembly that has an inner cartridge made up from a plurality of segments and an outer die. The semi-solid material is injected under pressure and high temperature into the die so that it flows into blade cavities defined between the segments of the cartridge. The cartridge is removed from the outer die and the segments are then separated to release the wheel.
