摘要
通过试验对比研究了亚温正火+弱水冷工艺对Q460C低合金高强钢板力学性能和金相组织的影响。结果表明:采用亚温正火和正火后弱水冷的方式,可以有效细化晶粒并减少内部缺陷,钢板的强度性能损失显著降低,断后伸长率略有降低,冲击韧性改善明显,冷弯性能良好。
The influence of NCC process on the mechanical properties, microstructure and cold bending property of Q460C Steel Plates for marine engineering was comparatively studied by experiment. The results showed that, after subcritical normalizing and weak water contrulled cooling proeess, the microstrueture was refined, the defects were reduced, and the strength loss of plates decreased obviously, the elongation decreased slightly, the low-temperature impact stability improved nhviously, and the cold bending property was good.
