摘要
针对 60 Si2 Cr VA弹簧钢拉伸试样不同的断口形态 ,讨论了拉伸试验过程中的应力分布情况和断裂过程 ,分析了产生不同断口的原因和机理 。
In view of different fracture forms of the tensile specimens of 60Si2CrVA spring steel, this article discusses stress distributions and processes of fracture during tensile test, analyses causes and mechanisms of different fractures, and points out abnormal fractures contribute to the decrease of area contraction.
