It is shown that deformation temperature is the main factor that influences the static recrystallization behavior. Carbonitride precipitation inhibits recrystallization and causes a plateau in the softening ratio curve. The static recrystallization activation energy of X80 pipeline steel was regressed and calculated to be 380 kJmol^(-1), and its rationality was also discussed according to previous references and investigations.

结果表明：变形温度是影响奥氏体静态再结晶行为的主要因素；微合金碳氮化物的析出抑制了再结晶的进行，使软化率曲线出现了平台；利用实验结果回归计算出了X80管线钢的静态再结晶激活能为380kJmol^(-1)，并根据文献研究讨论了结果的合理性。

It Was found that a complex ordered carbonitride is formed on hot-rolling and continuous cooling by the precipitation of Nb and V together with C and N in which the contents of Nb and V are changeable.

利用透射扫描电镜和能谱仪对Nb-V微合金化钢中Nb和V析出相进行了研究，发现Nb和V在高温形变和连续冷却中，与C，N形成一种复杂的有序碳氮化物，其中Nb与V的含量是可变的，其浓度比值C_(Nb/C_V随着析出颗粒尺寸的减小而递减，化学式可写成C_(1-x，N_(1-y)。
