The course is structured such that 2/3 of the subject is common and mandatory for all students while 1/3 consists of three modules of which the students must choose one.
Review of HSE and procedures for work at IMT`s laboratories. Measurement and analysis with emphasis on concepts such as accuracy, resolution, and Gauss' law on error propagation. Review of some generic measurement and analysis methods, both theoretical and practical (demonstration / lab / exercise): Thermal analysis (TGA, DTA, DSC and DIL in combination with MS) and X-ray diffraction(qualitative, quantitative, Rietveld, HTXRD). The general principles for measurement and control of temperatures will also be presented.
1. Electrochemical methods and nano-characterization: A review of standard equipment used in electrochemistry such as potentiostat, function generator and reference electrodes. Demonstration/review of several measuring techniques and analytical methods, both theoretical and practical: Current distribution, voltammetry, potential step, impedance spectroscopy and rotating disk. Nano-characterization will focus on AFM- and STM-techniques.
2. Working in ceramic materials: Refractory materials in the laboratory. Review of laboratory furnaces, types, construction, lining materials and heat elements with focus on applications and limitations. Processing of ceramics: A review of the various methods; from raw materials via powder synthesis to shaping methods and sintering. Vacuum technology and work in inert atmospheres will also be treated.
3. Scanning electron microscopy, EBSD (electron backscatter diffraction): to record and index diffraction pictures and present the results as orientation maps, pole figures, grain size distribution, phase distribution, misorientations and textures. Transmission electron microscopy (TEM): to characterize the microstructures (particles, grains and dislocations) in metal alloys by using bright field image, dark field image, and electron diffraction pattern, and determine the thickness of TEM sample by electron energy loss spectroscopy (EELS). Thermo-mechanical processing (rolling, heat treatment). Light optical microscopy. Digital image processing.
The course provides a general introduction to HES and risk assessment as well as a broad introduction to the basic experimental techniques and methods relevant to materials science, electrochemistry and materials chemistry. The theoretical foundation for the different measurement- and analysis methods will be reviewed. After completing the course, students should be able to make appropriate choices of methods for a given problem as well as being able to assess the accuracy of the measurement and to know which items are essential to make a good risk assessment.
Learning methods and activities
Lectures, compulsory exercises and demonstrations. The students are guided through a number of experimental methods and techniques essential for the research activities at the department. Lectures are given in English on demand.
Further on evaluation
If a student has to take the course over again, all evaluations in the course has to be repeated.
Exam registration requires that class registration is approved in the same semester. Compulsory activities from previous semester may be approved by the department.
Recommended previous knowledge
General and inorganic chemistry. Electrochemistry. Materials Science.
Required previous knowledge
The course TMT4300 Light- and electron microscopy is required for students who choose module 3: Electron microscopy
Compendium. Other potential course material will be announced the beginning of the semester.
