摘要
介绍了研究控轧控冷(TMCP)生产的Q370qD桥梁钢和 316L不锈钢制备的爆炸复合板热处理性能与组织演变过程.结果表明:316L/Q370qD(TMCP)爆炸焊接复合板低温退火后强度偏高延伸率较低,900℃高温退火后强度不合格、冲击值离散性大;优化热处理方案进行 630～710℃退火,最终确认适宜的热处理温度区间为 650～680℃、时间为1.5～2 h,大规格复合板退火(680℃/1.5h退火后空冷)验证测试性能合格,后续生产处理效果良好,表明TMCP状态的Q370qD桥梁钢与 316L不锈钢制备爆炸复合板具有可行性.
Abstract
The heat treatment performance and microstructure evolution process were investigated for the explosive clad plates combined by TMCP(thermo-mechanical controlled process)state Q370qD bridge steel and 316L stainless steel in the paper.The results indicate that the explosive welding 316L/Q370qD(TMCP)clad plates have the higher strength and worse plastic after the low temperature annealing,while the unqualified strength and large discrete of im-pact value are obtained after high temperature annealing at 900℃;the optimized heat treatment process are carried out in the range of 630～710℃,and the appropriate heat treatment temperature range is finalized as 650～680℃with holding time of 1.5～2 h.The qualified properties and good subsequent producing treatment effects are obtained for the large size clad plates after annealing verification testing(air cooling after annealing at 680℃×1.5h),which shows the feasibility of preparing 316L/Q370qD(TMCP)clad plates.
