Molybdenum wire has good properties such as high strength, high wear resistance, high melting point, low coefficient of expansion, good thermal conductivity and thermal conductivity, but its shortcomings such as room temperature brittleness and high plastic-brittle transition temperature greatly affect its processing and application. The lanthanum-doped molybdenum wire doped with a small amount of lanthanum oxide not only improved the structure and properties of molybdenum wire, but also strengthened the strength and toughness. Lanthanum-doped molybdenum wire preparation processes are as…
