摘要
Abstract
Fracture cause of 40CrNiMoA steel bolts was analyzed by means of macroscopic examination, fracture analysis, metallographic examination, hardness testing and chemical composition analysis. The results showed that the fracture mechanism was the hydrogen brittleness fracture, the reason of fracture was due to high absorption content of hydrogen during producing process of the bolts.关键词
