摘要
通过对试样进行低倍试验和金相显微组织观察,对AT25-6铁素体奥氏体双相钢产生脆裂的原因进行了系统地分析和讨论。通过试验分析表明,铁素体基体上分布有较多的σ相是造成本次AT25-6铁素体奥氏体双相钢产生脆裂的主要原因。
In this paper, the causes of brittle fracture of AT25--6 ferrite austenite dual phase steel were systematically analyzed and discussed by means of low-and-time test and microstructure ob- servation. Through the test analysis showed that the ferrite matrix on distributed more a phase is caused by the AT25--6 iron element austenite dual phase steel produce brittle fracture is the main reason.
