众多结晶体在低温环境下呈现解理断裂,在高温环境下呈现塑性断裂在过渡温区,解理断裂的应力随温度增加而增加,反映了屈服应力的下降以及裂纹尖端区塑性的相应增加.裂尖塑性可钝化裂纹并因塑性区中的压应力而屏蔽裂纹本文简短评述了脆一韧转变模型在该模型中,计算屏蔽效应的塑性区是由位错的产生、运动和相互作用形成的,...

The microstructure evolution has been investigated for hot rolling of advanced low carbon steels containing Nb, Ti, V and Cu. The critical processing step to develop the properties of hot rolled steels is cooling after rolling when the austenite-to-ferrite transformation as well as precipitation tak...
