扭折带扭折带kink band n iUZhedoi扭折带(k ink band)晶体受力时，如其取向不利于滑移和孪生，或者当晶体的塑性变形受到某些约束时而产生一种不均匀的局部塑性变形，形成一沦廓比较明显的楔形S状组织。诸如单晶体拉伸时受夹头的限制、不同滑移带的交叉、多滑移的同时开动、多晶粒金属相邻晶粒的相互制约、两相合金中两种相的变形不协调等，晶体就可能以扭折的方式变形。另外，拉伸或压缩时大应变的几何效应也能影响变形型式，这种行为在密排六方点阵金属或其他滑移系统少的晶体中尤为常见。 图1是密排六方点阵金属福单晶体受到压缩时的变形情况。晶体取向不利于底面(0。01)滑移，即此面上的分切应力为零时(图la)，晶体不能产生滑移方式的变形。于是为了适应这种压缩外力而发生了不均匀的局部塑性变形—扭折。图lb是扭折示意图，由图可见，扭折变形是一种与孪生不同的变形方式，其扭拆区的晶体取向发生的变化是不对称的，点阵发生折曲，而其左右两侧点阵则发生弯曲，折曲区的上下界面由符号相反的两列刃型位错(见滑移)所构成，而每一个弯曲区则由同号位错堆积而成，取向是逐渐弯曲过渡的，但左右两侧的位错符号相反。由此可见，扭折区原是一个由其他区域运动而来的位错汇聚的区域，位借F 耐贩 a T7f b 图1六方点阵晶体中扭折带的形成示意图 。一变形前;b一变形后 l一(0001)面;2一未变形区;3一扭折带;4一位错 FF喻1珊 FF ab 图2伴随孪晶形成而产生的扭折带示意图 1孪晶;2一协调扭折带;3一位移的汇聚产生了弯曲应力，使晶体点阵折曲和弯曲，从而促使扭折带的形成。扭折带的形成对晶体有两种影响:首先，晶体变短了，从而有助于与外力相适应，因此，有时也称为协调扭折(aeeommodation kink);其次，扭折区内晶体的取向与未变形区的不同，在前一区内，只要应力达到临界切应力爪，即能产生滑移。 孪生变形时也能形成类似的扭折带(图2)。虽然产生了孪生变形，但试验机的压头强迫晶体端部保持原来取向。而为了过渡，则往往依赖于在晶体一侧或两侧形成协调扭折带。由图可见，孪生的作用使试样端部趋于产生相对位移(a)，而扭折带的形成则使试棒适应千伏给年件的约束(b)。
