Short description
The course elaborates fundamentals of Materials Science, such as a general introduction, mechanical properties and related material testing of structural metallic materials. It gives a demonstration of specific damage mechanisms (creep, fatigue, creep-fatigue, corrosion). Welding of metallic materials and related problems is another focus.
|
|
Objectives
At the end of the course the students are expected to have basic knowledge about:
• structure of structural metallic materials
• influence of microstructure on material properties
• respective material test standards such as creep test, fatigue test and how to transfer the test results to components
• nature of specific damage and measures to avoid them at components
• changes in microstructure during welding and impact on material and component behavior
Target Attendees / Participants
University students of Steinbeis European Master Program in Risk Engineering and Management, and similar programs
