摘要:

采用SEM, TEM和物理化学相分析等方法对铁素体基Ti-Mo微合金钢在2种不同轧制工艺下的析出相分布和粒度进行了观察和统计, 结合热力学和动力学计算研究了γ相区变形过程中形变储能对诱导析出的影响, 分析了γ相区形变诱导析出量对后续γ→α相变以及相变后α相基体中继续析出时析出相的临界晶核尺寸、相对形核率和相对沉淀开始时间的影响.结果表明, 在总变形量相同的情况下, 与γ相再结晶区和未再结晶区两阶段轧制相比较, 采用γ相再结晶区单阶段轧制更有利于获得析出量大、尺度分布均匀的个位纳米级碳氮化物, 这类碳氮化物占析出物总量的75%(质量分数).

Abstract：

Single nanometer–sized particles, which are smaller than 10 nm, can significantly enhance the precipitation strengthening in microalloyed steels, thus causing their strength to be promoted greatly. In order to improve the strength of the steel, it is quite necessary to get a large amount of single nanometer–sized particles through optimizing rolling technology. In this work, the effects of two different kinds of controlled rolling technologies on the size and distribution of precipitated particles in the Ti–Mo ferritie matrix microalloyed steel have been researched using SEM, TEM and small–angle X–ray scattering. The results show that with the same total rolling reduction, the steel rolled only in γ phase crystallization zone can obtain a higher portion of single nanometer–sized particles than that rolled respectively in phase recrystallization and nonrecrystallization zones, in which those single nanometer–sized particles account for about 75% (mass fraction) of whole precipitated particles. In order to study the effect of deformation potency in γ phase zone on the amount of precipitates in phase and the micro–crystal size, nucleation rate and incubation time of following precipitates in γ→α transformation and ferritie matrix after γ→α transformation, some thermodynamics and kinetics calculations and analysis on precipitation are also conducted.

Key words： controlled rolling processing Ti–Mo microalloyed steel deformation potency nanometer–sized carbonitride
