The rapid development of industry on global markets and high production speeds pose various challenges for materials engineers. These challenges begin with the procurement of raw materials and semi-finished products or occur during the production process. The module ‘Process-accompanying analytics for quality assurance’ focuses on identifying analytical issues, making a criteria-based selection of analytical methods, understanding the interaction of different methods, taking into account the complementarity of the results and finally carrying out systematic process optimisation.

1 Rheology and flow properties of materials
1.1 Influence on the processing properties
1.2 Different methods for measuring rheological properties
1.3 Effect of recycled materials

2. surface analysis to evaluate the finishing of materials
2.1 Influence on the processing properties,
2.2 Different methods of surface finishing 
2.3 Influencing and determining the surface energy
2.4 Effect of recycled materials on finishing and resulting properties

3. analysis for defect description and process optimisation using imaging methods
3.1 Detection of microstructure, grain orientation, roughness
3.2 Extended application of standard methods: microscopy (digital microscopy and SEM), tomography (CT, 3D SEM)
3.3 Semi-automatic analyses (e.g. Image J or Stream/AnalySIS)
3.4 Recognising material or process-related material defects and deriving solution strategies

The total workload for the module is 150 hours (see also "ECTS credit points and grading").

• Portfolio exam

The portfolio examination (PFP) consists of 3 presentations during the semester in the form of a poster, lecture, short video unit, abstract, etc. Three different presentation formats must be chosen. One third of the overall grade is awarded for each presentation.

The portfolio assessment (PFP) consists of two semester-long presentations and a written work sample in the form of a poster, presentation, short video, abstract, etc. Students must choose from three different presentation formats.

Basic knowledge of materialography and analytical techniques. Knowledge of fractography.

Students who wish to refresh their knowledge and skills before starting the module are recommended to read the following basic literature:

Romeis, B. (2019). Mikroskopische Technik. Walter de Gruyter GmbH & Co KG.
Hunger, H. J. (Ed.). (1995). Werkstoffanalytische Verfahren: eine Auswahl; mit 39 Tabellen. Dt. Verlag für Grundstoffindustrie.
Oettel, H., & Schumann, H. (Eds.). (2011). Metallografie: mit einer Einführung in die Keramografie. John Wiley & Sons.

Students will be able to name various material and application-specific methods for process-accompanied analysis.

Students can identify errors early on in the various stages of processing and present solution strategies to remedy them.

Students can describe the selection, approach and implementation of these procedures in a differentiated manner and critically assess the results.

Students can independently individualise or adapt suitable analytical methods for in-process analysis.

The students discuss the task in small groups in a reflective manner. They can argue and critically communicate the results to specialists (potential clients).

Students can prepare the results in a scientifically sound manner and present and explain them in a suitable form.
