中文摘要：
由使用等温的双点击耐压试验并且使用 2% 偏移量方法，一个新模型被开发在温度预言忍受 Nb 钢的微结构进化在上面并且在导致紧张的降水的开始温度下面(T P ) 。T P 作为真紧张，起始的奥氏体谷物尺寸和 Nb 内容的功能被开发。静态的再结晶的活化能(Q 国王 ) 被表示为不同合金元素的内容的功能。Nb 在增加 Q 微结构观察和大小证实了的国王 模型的有效性在现在的调查发展了。
英文摘要：
By using isothermal double hit compression tests and applying the 2% offset method, a new model was developed to predict the microstructural evolution of Nb-bearing steels at temperatures above and below the start temperature of strain-induced precipitation （Tp）. The Tp was developed as a function of true strain, initial austenite grain size and the Nb content. The activation energy of static recrystallization （Qrex） was expressed as a function of the content of different alloy elements. It was found that Nb played the most important role in increasing the value of Qrex, The microstructural observations and measurements confirmed the validity of the model developed in the present investigation.
