摘　　要：研究了直接淬火、再加热淬火工艺下690 MPa级高强度结构钢的组织结构特征及其经630℃回火后性能的差异。结果表明,采用直接淬火加回火工艺,钢板具有更好的强韧匹配及耐回火性能。The microstructures of structure steel with yield strength 690 MPa directly quenched online and quenched in furnace were studied and the differences of properties when quenching plates tempered at 630 ℃ were also compared. The results show that the plate directly quenched and tempered.at 630 ℃ gains more excellent matching properties of strength, toughness and tempering resistance.

关 键 词：直接淬火 再加热淬火 回火 高强度结构钢
