一、钢铁的强化 1.强化的方向和理想强度所谓强度是对变形的抵抗。一般情况下,变形以滑移方式进行,滑移由位错的运动进行。施加应力使其变形时,如果能够运动的位错非常多,而且,位错源活化,位错易于大最增殖,则变形容易,强度低。相反,如果位错源和位错都非常少,在极端情况 First, the strengthening of steel 1. Strengthen the direction and the ideal strength The so-called strength is the resistance to deformation. In general, the deformation is carried out in a slip mode, and the slip is caused by the movement of dislocations. When stress is applied to deform it, if there are many dislocations that can move, the dislocation source is activated and dislocations tend to proliferate most and most, the deformation is easy and the strength is low. Conversely, if the source of dislocations and dislocation are very small, in extreme cases
