英文摘要	A study on the low-cycle fatigue (LCF) behavior of K416B alloy was conducted at 650 degrees C. According to the results, the LCF behavior of K416B alloy at 650 degrees C is mainly manifested as elastic deformation and the fatigue life of the alloy is determined by the level of material strength. When tension-compression fatigue occurs, the deformation mechanism of the alloy is reflected in the form of dislocation slip, and the deformation dislocations are bowed out in the matrix by Orowan mechanism, which leads to a dislocation configuration similar to the Frawk-Reed source. At the late stage of low-cycle fatigue, the fatigue-induced cracks develop from the alloy surface. As fatigue test proceeds, it is possible for the cracks to continue development along the regions of eutectic and the bulk M6C carbide due to stress concentration, thus causing the alloy to show cleavage fracture.
