0.23c-1.9mn-1.6si钢中的残余奥氏体对韧塑性的影响
Keywords: 金属材料,多相组织,残余奥氏体,冲击韧性,均匀延伸率,强塑积
Abstract:
？采用优化的iq&p工艺处理成分为0.23c-1.9mn-1.6si厚度为6.5mm的低碳硅锰钢,制备出由亚温铁素体、马氏体以及残余奥氏体构成、抗拉强度为1000mpa的多相组织高强钢。用sem、xrd、拉伸以及示波冲击等手段对其显微组织和力学性能进行表征,并与同等抗拉强度的iq&t钢和q&t钢对比,研究了钢中残余奥氏体对韧塑性的影响。结果表明,在室温下iq&p多相钢具有更高的冲击韧性、更好的延伸性能和强塑积,综合韧塑性要远优于其它钢种。该钢的性能,与其多相组织结构有密切的关系。大量弥散分布于铁素体和马氏体框架内的残余奥氏体在形变过程中发生trip效应,显著改善了钢的韧塑性,从而使其综合力学性能提高。
