摘要
对断裂试样断面宏观形貌分析、光谱化学成分分析、硬度测试分析以及金相分析,判定该脱硫增压风机空心轴为在运行中发生疲劳破坏断裂。
The paper did the macroscopic analysis, spectral analysis, hardnesstest, and metallographic analysis for the section of frac- tured sample, confirmed that fatigue failure fracture in operation was the reason for the hollow shaft of boost up fan fractured.
