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.
