摘要
Abstract
Three kinds of solid-solid doped molybdenum lanthana alloyed plates were prepared by first mixing molybdenum powder with an average size of 4. 0 μm and lanthanum oxide powder with an average size of 50 nm, 0. 5μm and 2 μm respectively, and then pressed, sintered and hot rolled into plates. The densities and crystal numbers of the sintered slabs, the longitudinal and transverse microstructures of the hot rolled plates and their tensile mechanical properties, deep-drawing properties at room temperature were studied. It is found that the solid-solid doped molybdenum lanthanide alloyed plates show an excellent performance, and that the variation of the average particle size of doped lanthanide oxide powders have a significant influence on the crystal numbers of the sintered slabs, and on the longitudinal and transverse microstructures, as well as on the tensile properties and deep-drawing properties of the final hot-rolled plates.关键词
