Abstract:

The feasibility of making an oxide dispersion-strengthened, cobalt-base alloy by mechanical attrition was investigated. The optimum blend of starting powders to produce a Co-20Ni-18Cr-1Y2O3 base composition was determined. Using this blend, four different alloys were produced two contained 1 and 2 Y2O3 and no aluminum, and two contained 1 and 4 aluminum with 1 Y2O3, respectively. A full scale property evaluation was performed for each alloy composition on extrusions produced at four different temperatures with a reduction ratio of 161. Modified author abstract
