马氏体形态的平行多层截面法研究柳永宁1,张贵一1,李伟1(1.陕西省西安市西安交通大学金属材料强度国家重点实验室)摘 要:设计了一种平行截面原位观察方法,并研究了一种C含量(质量分数)为1.37%的高碳钢的马氏体形态.采用激光打孔定位,超细抛光多层减薄方法原位追踪测量了目标马氏体的长度,宽度与减薄厚度的变化.以厚度累加变化为横坐标,测量的长度与宽度对称分布为纵坐标,还原出的马氏体空间形态为扁椭球体,而不是传统教科书中描述的透镜体,椭球的几何参数为a/b≈3,a/c≈20.热力学分析表明:形核能量除了与材料的物理......

用于描述奥氏体/马氏体界面的修正模型程宁1,郭正洪1,孟庆平1(1.上海市上海交通大学材料科学与工程学院)摘 要:在择优态存在的前提下,以修正Landau多项式描述奥氏体/马氏体的界面特征.以母相弹性模量,择优态能量和马氏体相变驱动力为参数,利用Ginzburg-Landau理论计算了奥氏体/马氏体的界面结构及相关性质.结果表明,奥氏体/马氏体界面存在一个序参量变化缓慢的平台,这个平台对应于点阵结构既非奥氏体也非马氏体的过渡区域.通过对奥氏体/马氏体界面宽度和界面能的计算,表明本模型可很好地解释一些实验中观察到......
