Two oxide-dispersion-strengthened (ODS) steels with different compositions (14Cr-ODS and 14Cr-Zr-ODS) were investigated to reveal the influences of microalloying element addition on the microstructure and to clarify the refining mechanism of precipitated particles. TEM and HRTEM results indicated that precipitated particles in the Zr-containing ODS steel had finer sizes and dispersed more homogeneously within the grains. It was found that rhombohedral Y4Zr3O12 particles with complex lattice structures were formed and could pin the migration of the grain boundaries during heat treatment due to their high thermal stability. In addition, the Zr-containing ODS steel exhibited a finer and more uniform grain morphology. Tensile tests showed that microalloying element addition could significantly improve the comprehensive mechanical properties of 14Cr ODS steels at room temperature.

This paper presents the testing campaign of the two First Wall mock-ups in the HELOKA facility, one mock-up having a 3 mm thick Oxide Dispersion Strengthened (ODS) steel layer on its surface and the other featuring a tungsten functionally graded cover. Special consideration is given to the diagnostics used for these tests, in particular, the measurement of the surface temperature of the tungsten functionally graded layer with an infrared camera. Additionally, the paper looks into the uncertainty associated with the calorimetric evaluation of the applied heating power for these experiments.

Abstract Ed Fagan Molybdenum Lanthanum Oxide, often referred to as lanthanated molybdenum, MoLa or ML, is an oxide dispersion strengthened alloy. It is produced by combining small amounts of lanthanum oxide (La2O3) particles with molybdenum. This creates a special stacked fiber microstructure that is stable at temperatures up to 2000 °C (3630 °F). After recrystallization, the elongated grain structure with jagged grain boundaries provides a measurable increase in ductility and creep resistant strength over that seen with pure molybdenum. Ed Fagan Molybdenum Lanthanum Oxide is the preferred material when embrittlement after recrystallization must be avoided. This alloy maintains its dimensional shape stability at high-temperatures. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as creep. It also includes information on wear resistance as well as heat treating and machining. Filing Code: Mo-21. Producer or source: Ed Fagan Inc.
