| 摘 要： | 采用微型样品测试方法测试了俄罗斯及国产合金化Mo-3Nb单晶的室温力学性能。结果表明：俄罗斯Mo-3Nb单晶屈服强度、抗拉强度、显微硬度比国产Mo-3Nb单晶要高，而延伸率略低；微观分析发现俄罗斯单晶基体Nb含量略高于国内研制的单晶且含有一定数量的棒状强化物。微观组织和成分的差异是引起2种Mo-3Nb单晶力学性能差异的主要原因。 |

| Abstract: | The mechanical properties of molybdenum with 3wt% niobium single crystal materials (Mo-3Nb single crystal material) were tested by miniature disk testing method. It is found that the yield stress, the fracture strength and the micro-hardness of Mo-3Nb single crystal materials by Russian supplying were higher than those of the home-made ones, while the elongations of the former material were lower than the later material. However, according to the TEM morphologies, Nb component in Russian supplying materials was a little more than that in the home-made single crystal materials, and some bar-type strengthening phases were observed in Russian supplying materials. Therefore, the difference of the microstructures and the component may cause the mechanical properties difference of the two materials. |
