Tungsten Reinforced Oxidation Resistant Columbium Alloys

Abstract

High-strength, oxidation-resistant composites are being developed for use in gas turbine engines at temperatures exceeding 2000F. In previous work a model system composite consisting of a CB-40Ti-9Cr-4Al matrix and W-3Re filaments was developed and tested. During the present period, testing of the model system was continued to further characterize this material. In addition, the matrix composition was modified to improve composite ductility. The improved matrix selected for use in the composite is Cb-42Ti-4Cr-4Al-1V. The composite developed has good oxidation resistance but is intended to be used in the coated condition with the oxidation resistance serving as a fail-safe protection.
