为了研究碳化物对GH3536合金冷变形损伤的影响并加以控制，通过薄带材的冷轧变形和圆柱试样的压缩变形，观察了碳化物破裂以及基体局部开裂的现象，并结合有限元模拟结果，进一步探讨了碳化物形貌与分布特征对组织损伤的影响。结果表明，当碳化物尺寸较大、形状不规则且呈团聚分布时，其内部应力与破裂倾向较大，而小尺寸圆形碳化物的情况与之相反。碳化物的团聚与条带状分布是引起基体应力和开裂倾向增加的主要原因。热处理结果表明，通过将热处理温度提高到1150℃以上，可以明显改善小尺寸碳化物的团聚和条带状分布特征，但对于10 μm以上的大尺寸碳化物改善效果不明显。

GH3536 alloy is a solid solution-strengthened superalloy for aero-engines. In general, this alloy is cold rolled into thin strips and used in honeycomb structures in engine sealing systems. During cold deformation of GH3536 alloy, a microstructural damage caused by carbide particles is the focus of attention. Therefore, understanding the influence of carbides on the cold deformation damage of GH3536 alloy is necessary to control such a phenomenon. Carbide cracking and local cracking of the matrix was observed through cold rolling deformation of thin strips and compression deformation of cylindrical specimens. Combined with finite element simulation results, the effect of carbide morphology and distribution characteristics on the microstructural damage was further discussed. Results show that when carbides are larger in size, irregular in shape, and distributed in agglomeration, the internal stress and fracture tendency are larger, which is contrary to small circular carbides. The agglomeration and banded distribution of carbides primarily increase matrix stress and cracking tendency. The heat treatment results show that the agglomeration and banded distribution characteristics of small carbides can be significantly improved by increasing the solution/annealing heat treatment temperature above 1150^oC, but the effect is not evident for large carbides above 10 μm.
