冷拔加工鋼管正是發(fā)生了加工硬化。冷拔時(shí)金屬發(fā)生塑性變形，晶體內(nèi)部有多個(gè)滑移系啟動，位錯(cuò)運(yùn)動彼此攔截，許多位錯(cuò)被釘扎住，造成位錯(cuò)塞積，同時(shí)位錯(cuò)源停止動作。上述一系列過程導(dǎo)致了位錯(cuò)的可動性降低，晶體中的位錯(cuò)密度顯著增加。 </div> <div id="wclte1u" class="para"> 當(dāng)塑性變形進(jìn)一步發(fā)生，應(yīng)力增加并足以使釘扎的位錯(cuò)開始運(yùn)動，螺位錯(cuò)交滑移，刃位錯(cuò)不能交滑移，這樣發(fā)生位錯(cuò)交截，使不動階數(shù)增加。 </div> <div id="csuxa2d" class="para"> 所以，通過冷拔加工金屬內(nèi)部位錯(cuò)密度增加，位錯(cuò)可動性降低，既難于產(chǎn)生位錯(cuò)又難于移動位錯(cuò)，因而金屬材料硬度、強(qiáng)度提高。這就是冷拔加工的金屬學(xué)原理。 </div></div><p><p><img
