本文综合研究所钼单晶体在范围很广的外界条件下的宏观蠕变规律及位组织。现有关于钼恒定蠕变的研究基本上是多晶体和在狭窄的温度,应力范围内进行的。本文研究是在温度450～2550℃和应力0.1～40公斤/毫米~2范围内对钼单晶体进行力学试验。试验时使晶体沿着(001)、(011)、(111)、(112)、(135)和(103)晶向受单向 In this paper, the macroscopic creep regularity and microstructure of Mo single crystals under a wide range of external conditions are studied. The existing research on the constant creep of molybdenum is basically polycrystalline and proceeds within a narrow temperature and stress range. In this paper, we study the mechanical properties of molybdenum single crystal in the temperature range of 450 ~ 2550 ℃ and the stress of 0.1 ~ 40 kg / mm ~ 2. During the test, the crystals were subjected to unidirectional (001), (011), (111), (112), (135) and
