Abstract
Low cost fabrication of integrally-bladed automotive turbine wheels using the gatorizing(TM) forging process was demonstrated. Basic forging parameters were developed for the nickel-base alloy IN 100. Several wheels were produced and post forging heat-treating studies were conducted to develop an optimum combination of stress-rupture and LCF properties. Target goals for these properties were higher than those achieved in this initial study. The capabilities and limitations of the forging process are defined along with an estimate of turbine wheel cost in large production quantities.
