With the increase of solidification velocity,the primary crystal phase Al2Cu undergoes a faceted-non-faceted transition.
结果发现,在凝固速度较低时,过共晶Al-Cu合金中初生Al2Cu相形貌大部分有明显的拐角,观察其平面,有的呈矩形,呈现小平面生长特性,随着凝固速度的提高,初生Al2Cu相的结晶特性由小平面向非小平面转化;而α-Al相与Al2Cu相共生生长时,Al2Cu相择优生长特性消弱,与α-Al相耦合生长,呈现非小平面-非小平面生长。
Geomagic software was used to deal with the point clouds and pick up the characteristic of the octopus solid model and then wrap, the model was reconstructed by means of Pro/E software’s facet feature and repeat style modules.
简要介绍了逆向工程的概念及其工作流程,通过三维结构光扫描仪得到章鱼实体模型的三维点云数据,再运用Geomagic软件进行多视点云拼合,特征提取,三角化后,利用Pro/E软件的小平面特征和重新造型逆向模块对章鱼实体模型进行建模。
