Abstract
This paper describes heat-treatment studies of forged compressor wheels carried out to determine whether wheels rejected due to low ductility could be salvaged by heat treatment. Adequate improvement in ductility was developed, by annealing about 100°F below the β transus, cooling at a low rate to the stabilizing temperature (1200°F), and stabilizing for a short time. The accompanying decrease in strength was slight.
