摘要
利用原子力显微镜观察并定量分析了铁基合金4种典型惯习面马氏体相变的宏观点阵变形特征。结果表明:{3,10,15}f薄片马氏体和{2,5,9}f透镜马氏体的宏观点阵变形呈一次均匀切变特征,其宏观点阵变形完全符合"不变平面应变"特征;而{2,2,5}f片状马氏体和板条马氏体的宏观点阵变形特征不符合"不变平面应变"特征。
The macroscopic lattice deformation characteristics of four kinds of typical martensite transformation in iron-based alloy were observed and quantitatively analyzed by means of atomic force microscope (AFM), and it showed that the macroscopic lattice deformation characteristics of these four kinds of typical martensite transformation are not the same. The {3, 10, 15}_f thin-plate shaped martensite exhibited 'N'-shaped macroscopic lattice deformation, which is in agreement with the concept of 'invariant plane strain'.
