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。
