等温时间对60Si2Mn钢下贝氏体组织性能的影响
Transactions of Materials and Heat Treatment(2014)
Abstract
通过热模拟实验和盐浴淬火处理,研究了60Si2Mn钢盘条奥氏体化后在300℃等温盐浴淬火时的组织演变规律及相应的力学性能,结果表明:在300℃等温盐浴淬火,形成下贝氏体,相变孕育期约为100 s,相变完成时间约为3000 s.随等温时间延长,材料抗拉强度缓慢降低,而面缩率不断增加,等温3000 s后,材料抗拉强度保持在1800 MPa以上,面缩率可达到50%.组织分析结果显示,下贝氏体由针状铁素体和纳米级条状奥氏体组成,起到提高材料韧性的作用.
