| 摘 要： | 由于原子力显微镜具有很高的横向分辨率和纵向分辨率，可以精确测定马氏体相变浮凸角，为马氏体相变切变角的精确测定奠定了基础。以Fe-30Mn-6Si形状记忆合金的应力诱发巴氏体相变切变角为例，利用原子力显微镜测出表现浮凸角，再经理论修正获得切变角。结果表明，原子力显微镜测定具有很高的精度和方法简便的特点。

| Abstract: | Atomic force microscopy (AFM) can be used for the determination of the relief angle on surface due to its high resolution in both transverse and vertical directions, which is the basis of accurate determination of the shear angle in martensitic transformation. In the present paper, the surface relief of the stress induced martensite in a Fe 30Mn 6Si shape memory alloy was measured by AFM and a correction method is proposed to calculate the shear angle from the measured apparent relief angle. The results show the sufficient accuracy and the easy procedures involved in the present analyzing technique |
