研究了GH4169 合金离子注入对蠕变/疲劳特性的影响，并应用应变能区分(SEP)法预测该合金在650℃的蠕变/疲劳寿命，给出了SEP寿命预测方程。试验结果表明离子注入法具有多种强化机制共同作用于合金使其强化，达到最佳的强化效果以延长使用寿命。
研究瞭GH4169 閤金離子註入對蠕變/疲勞特性的影響，併應用應變能區分(SEP)法預測該閤金在650℃的蠕變/疲勞壽命，給齣瞭SEP壽命預測方程。試驗結果錶明離子註入法具有多種彊化機製共同作用于閤金使其彊化，達到最佳的彊化效果以延長使用壽命。
연구료GH4169 합금리자주입대연변/피로특성적영향，병응용응변능구분(SEP)법예측해합금재650℃적연변/피로수명，급출료SEP수명예측방정。시험결과표명리자주입법구유다충강화궤제공동작용우합금사기강화，체도최가적강화효과이연장사용수명。
In the paper,the behaviors of creep/fatigue of ions implanted GH4169 superalloy were strdied.The predicted life on creep/fatigue of superalloy at 650℃ is gained,by strain energy partitioning(SEP) method.The results shown that several strengthening factors played a part in strengthening together when the high energy titanium ions implanted into GH4169 superalloy,and good benefits as prolonging service lifetime is achieved.
