Room-temperature Mechanical Properties of Mo-La_2O_3 Plate Prepared by Liquid-Liquid Doping AITranslate
Abstract AITranslate
The Mo-La2O3 slab was prepared by liquid-liquid doping and powder metallurgy,and then rolled into plate.After annealing at different temperature,the tensile strength of the Mo-La2O3 plate was tested at room temperature.The fracture surface of the Mo-La2O3 plate and its La2O3 content and distribution were analyzed by SEM and EDS.The results show that the elongation of the Mo-La2O3 plate is higher than pure molybdenum plate.The room temperature tensile strength of the Mo-La2O3 plate increases significantly with the La2O3 content increasing.The dimple-shaped fracture changes into a cleavage-type one with annealing temperature rising.La2O3 is distributed in the grain or on grain boundary,which can greatly reduces the impurity content on grain boundary,inhibit the growth of microscopic holes and micropores,and then improve the strength and toughness of molybdenum plate.
