When plastic deformation occurs, further stress increase and enough to make pinning dislocation movement, screw dislocation glide, edge dislocation cannot pay slip, thus occurred dislocation, increase the fixed order. Therefore, the hardness and strength of metal materials can be improved by increasing the internal dislocation density of the metal and reducing the mobility of the dislocation, which is difficult to generate dislocation and difficult to move dislocation. This is the metal principle of cold drawing.
