| 摘 要： | 采用X射线衍射(XRD)、透射电镜(TEM)和拉伸实验等方法,研究三种工艺制备的热轧TRIP钢残余奥氏体及其碳含量和稳定性.结果显示:贝氏体区停留时间对残余奥氏体量影响较大,当在贝氏体区模拟卷取时,残余奥氏体量最多；适当的增加弛豫时间,会增加最终组织中残余奥氏体的碳含量；残奥碳含量,还有残余奥氏体的形状和晶粒大小及周围...

| Abstract: | By means of X-ray diffraction(XRD),transmission electron microscopy(TEM) and tensile test,retained austenite and its carbon content and stability of hot rolled transformation-induced plasticity(TRIP) steels which were prepared through three processes was investigated.Result reveals that bainitic zone residence time has greater impact on the amount of retained austenite,the experimental steel obtained the maximum amount of retained austenite when it was coiled in the bainitic zone;the carbon content in retai... |
