<正>Steels, accounting for a large proportion of metals and their alloys, are still irreplaceable structural materials in industrial applications for a long time. Classical dislocation theory sheds light that strength can be enhanced by impeding the dislocation motion.Meanwhile, the ductility depends on the mobility of dislocation movement. As a result, one method of increasing strength or ductility always damages the other. In other words, there is a mutual exclusion between strength and ductility from the perspective of dislocation movement [1].
