摘要
运用扫描电镜、光学显微镜等检测手段对SA508Gr.3钢落锤试样的断口形貌和焊道热影响组织进行对比观察与分析,结果表明:落锤试样断口形貌与组织呈现出良好的对应关系,而且落锤试样的热影响区的组织韧性优于母材,并没有对母材产生不利影响。
The paper makes comparison and analysis of the fracture morphology and microstructure of HAZ with drop test on specimens cut from SA508 Gr.3 steel by scanning electron microscope and optical microscope. The results show that there are good corresponding relations between fracture morphology and microstructure. More over, the toughness of HAZ in drop test specimen is better than that of base metal, and has no adverse effects on the base metal.
