摘要
Abstract
The reason for fracture of lifting lug was investigated by observation on the appearance and fracture surface,analysis on chemical composition,and metallographic examination.The results show that the main reason for fracture is larger lifting speed or partial load.In addition,the high-level oxide slag and decarburization of the lug surface and carbonizing on the root surface may also affect the use performance of material.关键词
