Research to Develop Process Models for Producing a Dual Property Titanium Alloy Compressor Disk.
Abstract
This program is aimed at developing a science-based methodology for analyzing, optimizing, and designing metal-deformation processes to control microstructure and properties in a finished part. The validity and application of this approach will be demonstrated by developing forging process for a compressor disk from Ti-6242 alloy, as an example. Material behavior under processing conditions is being characterized by developing constitutive equations, formability and workability indices, and processing condition-microstructure-property maps. Computerized process models for axisymmetric deformation from rate-sensitive materials were developed. A test procedure for determining interface heat-transfer and friction coefficients was developed. The material, process, and interface models are being integrated in a system of computer programs for designing and optimizing the forging process for a compressor disk. Finally, the validity of these models will be evaluated by forging a sub-scale compressor disk from Ti-6242. (Author)
