摘要
Abstract
By means of chemical composition analysis,hardness testing,macro and micro examination,the cause of cracking in the thread roots of a nut was analyzed.The results showed that the cracking was due to the design flaw of nut,the undercut was designed for the parting surface of die forgings,resulting in non-forging organizations in the key parts of thread roots,and the strength was weakened.关键词
