課程概述

This course consists of intermediate- to high-level materials science lectures that introduce the basic concepts that are related to characterization and interpretation of texture. Also, the anisotropic properties of materials coming from texture will be briefly introduced. To be more specific, the course is divided into three main parts. The first part familiarizes the students with the representation of rotations and orientations using different mathematical approaches. The second part covers different methods to collect orientation data, e.g., via X-ray diffraction, electron backscatter diffraction (EBSD) etc. The analyses of the data will then be the next subjects. Typically, pole figures (PFs) and inverse pole figures (IPFs) are two most commonly-used tools, amongst others. Symmetries play an important role in terms of data interpretation and visualization. The third part of the course will be focusing on the application of texture on several different subjects, e.g., secondary recrystallization, additive manufacturing etc. Anisotropic materials’ properties that stem from texture will also be mentioned, with a focus on grain boundary characters and their distributions.

課程目標

Texture is encountered in almost every structural or crystalline materials, and has an impact on the behaviour of materials, being it large or small. From a broad view, the students should have an idea about how texture influences the physical properties such as electrical conductivity, magnetizability, or mechanical properties such as elasticity and plasticity etc. From the perspective of materials’ characterization, however, the ways to collect and analyze orientation data are universally applicable disregarding various end applications. To this end, various characterization methods will be demonstrated to the students, but detailed operation methods will not be covered. Then, how texture comes into existence is the question the students should be able to answer. There are also several cases where texture can be altered by manipulation of forming or annealing history of materials. Finally, the students should combine all that they have learnt to do a project case study. Alternatively, they can bring their own interested own topic or research project to the class, which shall nevertheless be related to texture and anisotropy.

課程要求

The students are expected to have taken the basic undergraduate course “Introduction to Materials Science and Engineering”, “Materials Analysis”, and “Physical Metallurgy”. It would be better if the students are familiar with matrices, tensors, and rotations.

評量方式
(僅供參考)

No.	項目	百分比	說明
1.	Group Project	35%	Few guidelines about the project will be given in the first class, which the students should follow in choosing the topic (possible topics given in class). Briefly, the project can be based on literature survey and review, or experimental data analyses on your own research subject. A written report must be accompanied by an oral presentation, which will be scheduled towards the end of the semester. Paper reports should include abstract of no more than 150 words, introduction, MAIN part, conclusion, and neatly-cited references etc. The MAIN chapter can be organized as Experimental, followed by Results and Discussion; it can also consist of several individual chapters or sections in a self-determined order. For the oral presentation, presentation slides will be shared with the whole class, which may be the source of the final oral exam. The overall 30 points of the project are divided up as 15 points for the written report and the other 15 points for the oral presentation. For the latter 15 points, the contents of the presentation, the presentation skills, and the abilities to address questions from the audience etc. will all be taken into account.
2.	Mid-term Exam	35%	Closed book; 3 hours, examination on course materials up to Week 7.
3.	Final Oral Exam	30%	Face-to-face interview form; lasting about 10-15 min each person; questions from fundamental to advanced; topics covering the contents from W1 to W15; sessions to be announced; you can get additionally 5 points if you speak English
