Failure Analysis on Mechanical Properties of a New Type of Low Carbon Bainite Spring Steel
摘 要
制备了一种新型低碳贝氏体弹簧钢并对其进行力学性能试验,结果表明其力学性能很差。采用化学成分分析、硬度测试、金相检验、夹杂物成分分析等方法对其力学性能差的原因进行了分析。结果表明:该低碳贝氏体弹簧钢中存在较多的夹杂物和铸造缺陷,造成了钢材成分不均匀且严重破坏了金属基体的连续性,导致该低碳贝氏体弹簧钢的力学性能变差。
Abstract
A new type of low carbon bainite spring steel was prepared and its mechanical properties were tested. The results show that its mechanical properties were very poor. The reasons for the poor mechanical properties were analyzed by means of chemical composition analysis, hardness test, metallographic examination, inclusion composition analysis and so on. The results show that there were many inclusions and casting defects in the low carbon bainite spring steel, which caused the uneven composition of the steel and seriously destroy the continuity of the metal matrix, resulted in the poor mechanical properties of the low carbon bainite spring steel.
