PROCESSING AND EVALUATION OF PRE-PRODUCTION QUANTITIES OF COLUMBIUM ALLOY SHEET

Abstract

The 0.155-inch B-66 sheet processed in the preceding report period was further processed to final gage, 0.050 inch. The yield of 46.4% from extrusion billet compares favorably with yields for other columbium alloys which are generally less difficult to fabricate. Sheet flatness was excellent and was 3.1% maximum. Gage uniformity was good, and AMS specifications were generally met; additional work is indicated to produce 1/2 AMS tolerances in the alloy. The FS-85 ingot, 6 3/8-inches in diameter and weighing 303 pounds, was readily forged to 2 5/8-inch thick slab and a high yield of material is expected from this operation.
