摘要：
This paper presents a study regarding the failure mechanisms in alloyed cast iron engine cylinder block by the analysis of the materials and stress distribution around the crack parts. The results show that abnormal microstructures and the nitrogen inclusions in the crack parts were detected and the stress is tensile stress in the crack parts and leads to a great potential risk of crack initiations. It is suggested that the abnormal microstructures, inclusions and the tensile stress are the main reasons for the formation and propagation of the cracks.
