摘　　要：从大量的现场试验中提炼板材拉伸和冲击试样断口的不同形貌特征，并加以比对分析，选择典型断口利用金相电镜等手段深入查找形成原因。对于在日常板材生产检验中正确识别断口，判断钢板质量状况有重要意义。The different fracture surface morphology in the tensile and impact tests had been reported in this paper. The typical fracture had been analyzed by scanning electron microscope（SEM） and microscope for analyzing the causes. In the daily inspection, this research was significant for identifying fracture and judging the quality of steel plate correctly.
