摘要
Abstract
The fracture reason of φ3.6 mm 55CrSi steel valve spring in dais experiment was analyzed by means of chemical composition analysis, metallographic examination and hardness testing. The results showed that the brittleness nonmetallic inclusion on the steel wire surface led to early fatigue fracture.关键词
