FGH95粉末镍基合金蠕变期间位错网的形成与分析
, PP. 838-844
Keywords: FGH95粉末镍基合金,蠕变,位错反应,位错网,衍衬分析
Abstract:
采用TEM观察和衍衬分析研究了FGH95粉末镍基合金蠕变期间的位错组态.结果表明,蠕变初期,1/2位错在γ基体{111}晶面开动,使位错不断增殖.蠕变稳态阶段,2组不同Burgers矢量的位错可能滑移至同一晶面并相遇,反应后形成六角位错网络,或在不同滑移晶面相交,形成具有四边形特征的位错网络.位错网的形成可降低位错可动性并抑制位错交滑移,提高合金蠕变抗力.蠕变后期变形特征是形变位错在γ/γ’界面位错网损坏处切入γ’相,切入γ’相的位错可发生分解,形成不全位错和层错的位错组态.
