| 摘 要： | 含Cu钢因具备良好的强度、耐蚀性、焊接性能,被广泛地应用于船舶、压力容器、石油生产平台及工程机械。但由于选择氧化,Cu在钢表面富集,易导致含Cu钢在生产过程出现热裂纹。针对含Cu钢的这一特性,采用热拉伸试验研究了Cu含量对钢高温塑性的影响,对相同Cu含量、不同Ni含量的钢种热塑性也进行了对比,并结合其显微组织及断口形貌对试验钢种的脆性断裂机理进行探讨。同时,还利用Thermocalc软件计算了试验钢种的塑性低谷对应温度,提出了含Cu钢的连铸工艺优化建议。

| Abstract: | Due to their high strength,anti-corrosion and good weldability,copper-bearing steels are widely used in industries of shipbuilding,pressure vessels,petroleum production flatform and engineering machinery.The copper in steel would be enriched in steel surface because of its selective oxidation,which would cause hot cracks in steel surface in production.Based on this characteristic,tensile tests were carried out to study the effects of Cu content on the hot ductility of copper-bearing steels.For the steel wit... |
