%X The growing process of thermal fatigue cracking in 3Cr2W8V steel was observed under desk SEM fitted with self-made minisized device for thermal fatigue test. Before growing of thermal fatigue crack, the main crack tip reveals to blunt firstly, and some holes and uncontinuous microcracks occur in front of it. The growth is developed by bridging of main crack together with holes and microcracks.
