除了用超晶胞,還有別的方法對置換固溶體進(jìn)行建模么?或者別的軟件來實現(xiàn)?

研究三元的合金體系,體心立方,Ti Nb Mo在格點出現(xiàn)的幾率分別為 76% 20% 4% 查了很多文獻(xiàn),對建模方面都略過去了,不知道怎么實現(xiàn)的,如果超晶胞,這個計算量也太大了吧? |

我都讓你搞糊涂了,這個應(yīng)該一想就明白的! 首先,你的問題是添加原子的問題。某個位置已經(jīng)有了一個原子,不管你再添加一個什么樣的原子,都不可能在同樣的位置添加啊。所以你要新加一個原子,肯定要把坐標(biāo)更改的。 然后,來說混合原子的添加。虛擬原子不能通過直接add atom的方式添加,你可以先添加例如Fe,然后選中這個Fe,在左面的屬性里找到composition,在這里面可以把其他組分及濃度加進(jìn)來。不要修改add atom時的占居比例 |

謝謝,ms里的幫助文件看到了,就是這么做的 ![]() many thanks!!!Creating and editing mixture atoms Mixture atoms may be used to simulate the case where one atomic site is randomly occupied by two or more different types of atom. Materials Studio allows you to create mixtures of different elements, oxidation states and isotopes. To edit the selected atoms as mixture atoms Choose View | Explorers | Properties Explorer and select one or more atoms. Double-click on the IsMixtureAtom property to display the Edit Mixture Atom dialog. To edit a component of the mixture atom Highlight the appropriate component in the list and click on the Edit button to display the Edit Mixture Component dialog. To change the element type you may either type the element symbol directly into the box, select an element from the dropdown list, or click the button to display the periodic table. To change the isotope, select the desired mass number from the list of known isotope in the dropdown list. Natural refers to the element having an isotopic mixture in naturally occurring abundances. To change the composition, enter a value between 0.0 and 100.0 in the box. Note that the total composition of all components must add up to 100% and so it may be necessary to adjust the compositions of other components. Materials Studio will perform a scaling for you, but the results may be undesirable. To change the oxidation state, enter the value between -5 and +8 in the box, or use the spin control. To add a component to the mixture atom Click the Add button to display the Edit Mixture Component dialog and follow steps 2-5 above. To delete a component of the mixture atom Select the component to be deleted in the list, and then click the Delete button. Further information About disorder Edit Mixture Component dialog |
