Abstract Scope Resistance to elevated temperature creep deformation is an important characteristic for high temperature furnace applications. This work evaluated creep deformation of ODS Molybdenum-Lanthna sheet at two Lanthanum concentrations 0.6 & 1.1%. Testing methods are applied for screening the effects of process variations on the deflection resistance capabilities in sheet bending of molybdenum and Mo alloys at temperatures up to 1550°C. The first stage of the testing evaluated the room and elevated temperature tensile properties of commercially available Mo & Mo alloys that are applied in high temperature furnace. Second Stage of testing evaluated the bending deformation in a multi-cycle dead weight 3-point bending configuration of ODS Moly-Lanthana. Sheet material was produced via powder metallurgy technique with thermal mechanical processing. Results of this testing will provide insight on the temperature-stress level capability for designing applications of these materials in furnaces.
