摘　　要：采用GB/T15260—94B法(即铜-硫酸铜-16%硫酸测定镍基合金的晶间腐蚀敏感性的方法)对国产Incoloy800H传热管在不同条件下的晶间腐蚀试验结果进行研究,并与进口Incoloy800H合金管的抗晶间腐蚀性能进行对比。分析结果表明,影响合金抗晶间腐蚀能力的主要因素是C、Ti含量,其敏感性随C含量的增加而递增,加入Ti元素是降低晶间腐蚀敏感性和防止晶间腐蚀的有效措施。By using GB/T15260-94 B method, i.e., copper - copper sulfate -16% sulfuric acid evaluates intergranular corrosion sensitivity of nickel-based alloys, the intergranular corrosion test results of domestic heat transfer Incoloy800H tube of High-Temperature Gas-cool Reactor（HTR） nuclear power plant demonstration project are studied under different test conditions, and compared to the intergranular corrosion performance of imported Incoloy800H alloy tube. The results show that the main factors to influence the alloy resistance to intergranular corrosion are C and Ti contents, and the sensitivity increases with increasing of C content. The effective measure to prevent intergranular corrosion is to add Ti element to reduce the sensitivity to intergranular corrosion.
