研究了Ti-8wt%Fe(Ti-8Fe)合金中α析出物的结晶学特征。观察到析出物呈现板条状形态，其习惯面定义良好，包含一组位错。用透射电子显微镜表征了析出物与基体的取向关系、板条的拉长方向、惯性面的取向以及惯性面内的位错结构。用O线模型解释了析出物的这些结晶学特征。用分子动力学方法计算了不同O型线界面的界面能。计算结果显示了一个相当平坦的低能区。惯性面的界面能落在这一区域，这表明低的界面能可以解释观察到的钛合金中析出物的结晶学。这也意味着α析出物的结晶学的真实散射。对其他钛合金的结果进行了讨论，并对其进行了类似的解释。
Crystallography ofαprecipitates in a Ti-8 wt% Fe (Ti-8Fe) alloy is investigated in this study. The precipitates were observed to exhibit a lath morphology with a well-defined habit plane containing a single set of dislocations. The orientation relationship between the precipitates and matrix, the elongated direction of the lath, the orientation of the habit plane, and the dislocation structures in the habit plane have been characterized using transmission electron microscopy (TEM). These crystallographic features of the precipitates were interpreted by the O-line model. The interfacial energy of various O-line interfaces was calculated using molecular dynamics. The calculated result shows a rather flat low energy region. The interfacial energy of the habit plane falls in this region, indicating that low interfacial energy can account for the observed crystallography of the precipitates in this titanium alloy. It also implies true scattering of crystallography ofαprecipitates. Results of other Ti alloys are discussed, and they can be similarly explained.
