摘要
某型0Cr12Mn5Ni4Mo3Al钢制弹簧在进行低温试验过程中发生断裂。通过断口分析、金相检验和能谱分析进行了综合评定。结果表明:弹簧的断裂性质为脆性过载断裂;弹簧断裂的直接原因是弹簧材料中含有较多的脆性夹杂物。
A 0Cr12Mn5Ni4Mo3Al steel spring fractured in low-temperature steel system test.Using fracture analysis,metallographic examination and energy spectrum analysis to comprehensive evaluate.The results showed that the spring fracture properties was brittle fracture and the direct cause of fracture was spring materials contained more brittle inclusion.
