可以重复往返大气层的空间飞行器和高超音速飞机的耐热结构零件和部件的连接和固定都需要使用各种紧固件,它们必须能够承受得住1300℃的高温,其中包括氧化环境和结构载荷引起的应力。在完成使命的整个过程中,亦应考虑静态拉伸和剪切应力作用,但是,以飞行过程中的受热更为重要。蠕变行为也是一个 Spacecraft and hypersonic airplanes that can be re-exposed to atmosphere are required to be attached and secured to the heat-resistant structural components and components by using a variety of fasteners that must withstand temperatures of 1300 ° C, including oxidation and structural loads Stress. During the entire mission, static tensile and shear stress should also be considered, however, the heat in the flight is more important. Creep behavior is also one
