Abstract利用纳米压痕仪,OM, SEM, TEM, XRD, EPMA等设备研究了加氢反应器用2.25Cr-1Mo-0.25V钢正火态粒状贝氏体组织及力学性能随回火温度的变化.结果表明,2.25Cr-lMo-0.25V钢正火后得到由贝氏体铁素体、马氏体和残余奥氏体岛(M-A岛)组成的粒状贝氏体组织.纳米压痕测量结果表明,由于M-A岛中富集C,其硬度显著高于贝氏体铁素体.在回火过程中,M-A岛分解和贝氏体铁素体软化的综合作用导致了2.25Cr-lMo-0.25V钢在-18℃的冲击功随着回火温度的升高先增加后减少.除了铁素体基体回复再结晶软化效应外,粒状贝氏体组织中硬相M-A岛回火转变程度以及析出碳化物形貌、尺寸和分布是影响2.25Cr-lMo-0.25V钢冲击韧性的关键因素.
