JEMS软件在《材料现代研究方法》实践教学中的应用

Application of JEMS software in teaching"Modern Research Methods in Materials"

《材料现代研究方法》作为理论教学与实践教学相结合的课程,在材料科学与工程课程中占有重要的位置。其中透射电子显微学部分学习难度较大,应用到科研实践时往往教学和实践有一定差距。为了解决该问题,将JEMS软件应用到《材料现代研究方法》教学中,利用该软件对7000系铝合金中η′(MgZn_(2))相进行了选区电子衍射模拟和高分辨像模拟。结果表明:JEMS软件可以将《材料现代研究方法》教学中难点进行可视化处理,让学生更容易理解透射电子显微学,为以后科研工作打下基础。

"Modern Research Methods in Materials,"as a course combining theoretical and practical instruction,plays a significant role in the curriculum of materials science and engineering program.Among the characterizations used by the course,Transmission Electron Microscopy(TEM)is a challenging topic to students and there is sometimes a disconnection between theory and practice when applied to research practice.In order to solve this problem,this study employs JEMS software in the teaching of"Modern Research Methods in Materials"to perform selected areas electron diffraction simulation and high-resolution image simulation for theη′(MgZn_(2))phase in 7000-series aluminum alloys.The findings demonstrate that the JEMS software can visualize the challenging parts in the teaching of"Modern Research Methods in Materials",thus promoting students’understanding on TEM and establishing the foundation for their further scientific investigation.
