| 英文摘要 | Low carbon tempered martensite structures in the surface of Ni-Cr-Mo-B ultra-heavy plate steel was studied. The toughness at different locations in the surface zone was investigated by impact testing, and the sub-microstructures, such as packets and blocks of the martensite, at different distances (3, 15 and 25 mm) from the surface were observed by OM, SEM and electron backscattered diffraction (EBSD), and the dislocation density were tested by XRD and positron annihilation spectroscopy (PAS). The results indicate that the toughness of the tested steel in the 10 mm from the surface deteriorates sharply, which is mainly due to the bigger packet and block size and higher dislocation density in the tempered martensite. |
