　　對失效金屬波紋管裂紋
、斷口以及加工過程等情況進行初步分析後
，判斷該裂紋和斷口與材料成分分布不均有關。

　　1.破損原因判定

　　材料分析結果表明，材料的化學成分和力學性能均符合GB/T3280-2007標準的規定。金相分析結果顯示
，材料為正常奧氏體組織；daizhuangzuzhicunzaishiyouyujinshubowenguancailiaojinglengjiagongchengxinghouziranchanshengde。liewenquhongguanchengneiaowaituxingtai。weiguanxingmaoxianshiweitongtouxingjizuzhituoluodetezheng。zaituoluozuzhidebianyuanjiqiqianbiaomianduanmianjuncunzaichengmijijilianzhuangfenbudejiazhahuojiazawu。jiazawudecunzaipohuailejitizuzhidelianxuxing。dangbowenguanneibiaomianshouyashi，waibiaomianchengshoulayinglizuoyong，daozhiquexianquyujubutuoluo。
