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.
