Learning objectives Materials Sciences 2
After the course the student should be able to:
- Predict the microstructure of simple iron alloys and other alloys with reference to phase diagrams and time-temperature-transformation diagrams;
- Explain the course of phase transitions such as solidification, precipitation and martensite formation;
- Explain how and why the microstructure of iron, steel and other alloys needs to be modified to ensure reliable material behavior at very high and low temperatures;
- Recognize the main corrosion mechanisms and suggest possible ways of preventing corrosion.
This is a part of module 3, ME 3 Energy and Sustainability of the Bachelor Mechanical Engineering. See here for the complete description of the module.
Content Materials Sciences 2
For the design and manufacturing of installations and tools it is important that the right material is selected. Only then a designed product works properly. But how do you choose well? Where does the choice depend on?
There are various materials classes, such as metals, plastics, ceramics and composite materials, each with their own pros and cons. But within each class hundreds of materials are available. Materials Science 1 and 2 provide insight and background information to make a responsible material selection. By understanding how materials are built up (material structure) and how the materials react to the conditions of use (constant/varying applied stress, low/high temperature, environment, etc.), it becomes clear in which direction to go. An advanced computer program helps in making the material selection.
The importance of the relationship between materials, properties and production methods was presented in Materials Science 1 and this relation is further elaborated in Materials Science 2. Much attention is paid to iron and steel alloys, phase transformations and various heat treatments. In addition, materials applied at relatively low and high temperature materials are studied. Finally, the causes and effects of (high temperature) oxidation and corrosion are discussed.
Non-ME students can take this course if they meet the entry requirements.
