摘　　要：C-HRA-1是700℃超超临界锅炉受热面的重要备选材料,国内制造企业对其加工性能的研究尚处于起步阶段。通过对C-HRA-1材料进行拉伸制造了不同变形量的试样以模拟实际生产过程中的冷加工变形,利用箱式电阻炉对不同变形量的试样进行了不同参数的固溶处理试验,考察了其热处理前后的硬度,金相及晶间腐蚀性能,探讨了该材料在实际生产过程中冷加工变形后的固溶处理工艺,为C-HRA-1材料在700℃超超临界锅炉中的应用提供参考。C-HRA-1 is an important candidate material of 700 ℃ A-USC boiler heating surface, the research on its manufacture properties by domestic manufacturing enterprise is still on the primary stage. In order to simulate the cold working deformation in manufacturing, we make samples of various degree deformation by tension tests. Then the solution treatment with various parameters are carried on these samples in Box-type electric furnace. The hardness, metallography, and intergranular corrosion resistant of the samples before and after the solution treatment are examined. In this paper, we discuss the heat treatment process after cold working deformation of C-HRA-1, which can provide references for the use in 700 ℃ A-USC boiler.
