Development of Hot Isostatically Pressed Rene 95 Turbine Parts. Addendum.

Abstract

This report deals with the results of Task VI - Cooling Rate Analysis for Optimum Properties - of Contract DAAJ02-73-C-0106, Phase II, aimed at better undestanding the critical heat treatment involved in the powder metallurgy production process for manufacturing premium quality hot isostatically pressed (As-HIP) Rene 95 engine hardware. The initial heat treatment study on test blocks and test specimens determined the effect of section size, quench media, and solution temperature on cooling rate from two different solution temperatures. The correlation between cooling rate microstructure and mechanical property was then established using test specimens. The turbine disks heat treated with different solution temperatures, quench media, and with or without a bore hole defined the most desirable heat treatment parameters for achieving properties. The disks, first heat treated improperly but followed by the selected heat treatment, revealed that the double heat treatment may improve the mechanical properties of the disks initially heat treated improperly.
