Evaluation of Oxide Dispersion Strengthened (ODS) molybdenum alloys

Abstract

A series of fourteen (14) novel high-strength molybdenum alloy compositions containing a dispersion of very fine (98% cold work) condition and for as-swaged material in the heat treated condition. Extremely fine oxide particle sizes (<1000 {Angstrom}) were observed by Transmission Electron Microscopy (TEM) for a number of the experimental compositions in the as-swaged condition. A one hour recrystallization temperature as high as 3990{degrees}F was measured and a ductile-to-brittle transition temperature as low as {approximately}58{degrees}F for material in the recrystallized condition was determined. The preliminary results support the alloy design concept feasibility
