摘要
利用Gleeble3500热模拟试验机,结合光学显微镜,研究双相钢在不同变形量和保温温度条件下的相变行为及组织演变规律。结果表明:变形量和保温温度对第二相的体积分数均有影响,随变形量的增加,保温温度的降低,第二相的体积分数增加。当冷却速度为25℃/s时,保温温度选择450～500℃,可以得到较为理想的组织。
Transformation and microstructures of dual phase steel with different deformation reduction and holding temperature were investigated by using the Gleeble3500 thermal-mechanical simulator and optical microscope.The experimental results show that deformation and holding temperature affect the volume fraction of second-phase.The second-phase fraction increases with increasing deformation reduction,and decreases with increasing holding temperature.The optimum holding temperature should be 450~500 ℃ at the cooling rate of 25 ℃/s.
