H 13材料的显微组织均一，发生均匀腐蚀，多相的铁基超合金和钴基超合金显微组织中化合物相比固溶体相耐锌腐蚀性能好。
Uniform corrosion happened on homogeneous H13. Corrosion resistance of compound phase is better than solid solution phase, whether in Fe-based superalloy or Co-based superalloy.
在裂纹较小阶段，疲劳小裂纹的扩展受显微组织与多相界的影响。
When the crack is small, the fatigue crack growth is obviously influenced by microstructure features and multiple phase boundaries.
