DEVELOPMENT AND PRODUCTION OF IMPROVED MOLYBDENUM SHEET BY POWDER METALLURGY TECHNIQUES
Abstract
Mo-Ti and Mo-Ti-C sheets rolled from slabs sintered at 2150 C were evaluated for composition, recrystallization temperature, tensile properties at room-temperature and 1200 C, 1200 C stress-rupture properties and ductile-brittle transition temperature. The results were examined along with results from previous sheet evaluations. The dependency of sheet properties on variations in alloy form and concentration and sintering conditions was determined. The sintering temperature of the slabs had the greatest effect on sheet properties. The test results verified that high-temperature properties of powder-metallurgy sheet produced from a mixture of Mo with 0.5% Ti and 0.1% C sintered at 2150 C are superior to those of the compositional counterpart sintered at 1800 C and to those of commercial arc-cast Mo-0.5Ti-C sheet.
