摘要
分析了80#钢成品盘条出现自然断裂的原因。认为组织中含有大量针片状马氏体和羽毛状上贝氏体组织,是造成80#钢失效的主要原因。控制冷速是改变脆断的主要措施。
It is analyzed the reason for breakdown of finished wire bar of 80# steel,considered that there is a large quantity of flaky martensite and feather-like upper bainite in the structure is the main reason for failure of 80# steel. The main improving measure is to control cooling speed.
