The results show that the main reason for the cracking was high temperature intergranular oxidation, with the fracture morphology being a typical intergranular cracking character.
结果表明，造成主蒸汽滤网开裂的主要原因是晶界高温氧化，断口呈典型的沿晶开裂特征。
The oxidation degree of grain boundaries and crack propagation are qualitatively analyzed based on crack density and percentage of intergranular crack.
用裂纹密度和晶界裂纹的比例对晶界氧化的程度及裂纹扩展情况定性地加以分析。
