Feasibility of Making an Oxide Dispersion-Strengthened Cobalt-Base Alloy by Mechanical Attrition.
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 16:1. (Modified author abstract)
