After successful completion of the course, students are able to...

• Explain the difference between crystalline and amorphous solidification
• Name the structural features of polymers that influence the melting and/or glass transition temperature and explain the methods used during morphological characterisation
• Describe the inequilibrium for the metastable system iron-iron carbide (Fe-Fe3C) using time-temperature conversion diagrams and discuss their application to the hardening of steel
• Perform bending tests, which are better suited to the characterization of brittle materials than tensile tests
  

Test methods for the materials:

• Transformation Hardening of Steel
• Structure and Morphology
• Differential Scanning Calorimetry (DSC) and Dynamic-Mechanical Analysis (DMA)
• Bending Tests

Dilatometric determination of microstructural transformations in a steel sample

Bending tests on specimens made of sintered steel and processed using powder metallurgy

Microscopic observations of the heating (until melted) and cooling (at a defined cooling rate) of a polypropylene sample. The average spherulite size within the crystallized sample is then determined

DSC- and DMA-based characterisation of the heating (until melted) and cooling (at a defined cooling rate) of a polypropylene sample. Characteristic properties including melting temperature, modulus of elasticity-temperature curve and glass transition are then determined.

Dear students!

We will attempt to conduct the laboratory course in person as is custom for this exercise. However, if this is not possible, the laboratory course will be completed ONLINE in its entirety.

Registration of groups should be completed in TISS. Further information on how this can be achieved is available in TUWEL. Four (4) places are available in each laboratory course group, which are numbered 1-21. You will be informed if circumstances dictate the necessity of a switch to ONLINE mode. If this were to occur, groups 3, 6, 9, 12, 15, 18 and 21 will be divided, distributed across the other two groups and run on the same day.

This ensures that the laboratory course can be conducted without issues. Division will be completed alphabetically. ONLINE laboratory courses would be conducted in the same way as they would in person i.e., questioning, completion of tasks + discussion and protocol (as homework).

I will be available for all questions on 3.10.22 at 1.00 p.m.!

This course is supported by TUWEL (TU Wien E-Learning).

To access the online resources for the course please complete the following steps:

1. Subscribe to the course.
2. The course schedule and relevant associated details can be found under "Documents". Be sure to read this information thoroughly before registering! Registration is possible from 02.09.2022.
3. If you attend the course 372.012 (Basics of Electrical Engineering and Electronics for Mechanical Engineering), you should ensure that the scheduled experimental dates for your desired group do not clash with the dates scheduled for the other laboratory exercises.
4. Register for a course group. Registration is binding.
5. Once your registration has been confirmed by the course instructor, you will be able to access the online resources associated with the course. You will receive confirmation of registration from TISS via email.
6. Following confirmation of registration (at latest: 4.10.2022) you will also be able to access TUWEL. Log in with the following data: login: matriculation number, password: yourTUPassword. You will find continuously updated information and documents for all laboratory exercises associated with the course in TUWEL. When accessing the TUWEL course for the first time, please use the above link (to the TUWEL online course)!
7. All students who have already completed the laboratory exercise "Transformation Hardening of Steel" in the laboratory course "Fundamentals of Materials Engineering" and have a certificate attesting as much for the entire exercise are not required to repeat this exercise of the course again. Please send your certificate and the group number for which you are registered to heinz.kaminski@tuwien.ac.at.

9. Groups 19-21 will be held in English

Example questions:

What is a spherulite?

How can the glass transition temperature be determined experimentally?

Which effects can be detected using thermal analysis?

Which test configurations are possible during a bending test?
