Fracture is the most common failure modes of the crankshaft, under normal circumstances often result in serious consequences. So study the reasons for the crankshaft fracture, thus achieving the purpose of controlling and reducing accidents, is very realistic. In this paper, for example, a factory break 4M16 compressor crankshaft. Through micro-analysis of the crankshaft fracture, the 4M16 compressor crankshaft is a low stress fracture of brittle fracture .The fracture is mainly due to dendritic segregation cause tissue caused by uneven. Solution to the problem is to increase the ratio of forging the forging, heat treatment when the grain refinement.
