中文摘要
本文主要探討鍋爐二次過熱出口爐管TP-304劣化，利用電子顯微鏡觀察破孔斷面金相組織及探討腐蝕之影響因素，破損劣化主要原因是由於油灰腐蝕與潛變現象，導致管壁外層氧化物損耗。
英文摘要
A metallurgical exmination was performed on a failed Secondany superheater tube from steam Power Station. The prupose of the examination was to determine the probable cause of the failed secondary superheater tube. The failure of the stainless steel secondary superheater tube was attributed to oil ash corrosion and creeping which resulted in stress ruptrure of the tube metal due to loss of oxided layer material on the external side of the tube.
