Basics of dislocation structure are presented , beginning with a historical overview of how dislocations were discovered 將由差排如何被發(fā)現(xiàn)的歷史開始回顧,說明差排結(jié)構(gòu)的基礎(chǔ)。
O - lattice model is userful for calculation of interface dislocation structures . this tool box gives some general interfacial dislocation structures which may be helpful for learning o - lattice model and making some simple calculation 此scilab工具箱提供了一些常見界面的位錯結(jié)構(gòu)模型,可以便于學習o點陣和進一步研究其他界面使用。
Based on the microscopic tem and sem observations , relationships between dislocation structure and rate - dependent / rate - independent behaviors under certain range of temperature and strain rate were presented . interactions between grain boundaries and dislocations were analyzed 利用tem 、 sem分析手段,觀察到一定溫度和應(yīng)變速率區(qū)間內(nèi)率相關(guān)與率無關(guān)變形的位錯組態(tài)區(qū)別,及晶界對位錯的不同作用。
Presents the microstructure evolution in aluminum a nd copper after deformation by cold rolling in the strain range of 10 to 50 % red uction using tem and points out three types of dislocation structures are typica l and two of them are common for both materials and these two common types are f ound in non - cube grains and can be distinguished by crystallographic orientatio n of dislocation boundaries in the grains and the third type of structure is obs erved in cube grains , and concludes that grain orientation is important in deter mining the structure type but some other metallurgical parameters also have a ro le to play 采用tem對冷軋多晶銅與多晶鋁的形變顯微組織演變進行了對比研究.結(jié)果發(fā)現(xiàn):多晶銅及多晶鋁形變顯微組織中均含有三類典型的位錯結(jié)構(gòu)類型,其中的兩種結(jié)構(gòu)特征在兩種材料中是相似的,這兩種類型結(jié)構(gòu)存在于非立方取向晶粒,可通過晶粒中位錯邊界的晶體學取向加以區(qū)別,另一類型結(jié)構(gòu)存在于立方取向晶粒;晶粒的晶體學取向決定了其形變顯微組織類型,但其它冶金學因素對顯微組織也有影響
