摘要
本研究详细观察并半定量分析了铁素体球铁疲劳裂纹萌生、长大直至破坏的全过程,同时从断裂力学的角度作了考察。
The detail observation and quantative analysis are made on the formation and developmentof fatigue cracks in ferrite nodular irons.The experiments are made on the process of formation,de-velopment and failure,at the same time,are investigated based on fracture mechanics.
