在Gleeble热模拟机上采用应力松弛方法，研究了一种NbTiV微合金化钢奥氏体应变诱导析出行为，结果表明：实验钢的沉淀析出PTT曲线是典型的“C”曲线形状，沉淀发生具有一个最快析出温度，大致在900－920℃奥氏体预变形加速沉淀析出过程的进行，使PTT曲线向左上方偏移，奥氏体中的沉淀相形貌有球形和方形两种，其中方形沉淀相是均热过程中的未溶质点，以TiN为主，球形沉淀是应变诱导析出相。
The stress-relaxation method was used on a Gleeble thermal simulator to study the strain-induced precipitation behavior of austenite in NbTiV microalloyed steels. The results show that the precipitated PTT curve of the experimental steel is a typical “C” curve shape with one The fastest precipitation temperature, roughly 900-920 ℃ austenite pre-deformation accelerated precipitation process, the PTT curve shifted to the upper left, the precipitated phase in austenite spherical and square two, of which square The precipitated phase is the non-solute point in the soaking process, mainly TiN, and the spherical precipitate is the strain-induced precipitated phase.
