英文摘要The thermal fatigue behavior of K125L superalloy at the peak temperature of 1,050 A degrees C was investigated by optical microscope (OM), X-ray diffraction (XRD), and scanning electron microscope (SEM). The experimental results show that the crack initiation sites of tested alloys are at the V-notch tip and the V-notch tip propagates by way of continuous cracking along grain boundaries. The formation of high-temperature oxides and MC carbides accelerates the crack propagation, and no secondary carbides precipitate out. Oxides between cracks are mainly the Al2O3 as well as Cr2O3, and carbides are Ta-rich and Ti-rich MC carbides.
