KurzbeschreibungThis course provides a basic foundation in materials science for mechanical engineers. Students learns how to select the right material for the application at hand. In addition, the appropriate processing-microstructure-property relationship will lead to the fundamental understanding of concepts that determines the mechanical and functional properties.
LernzielAt the end of the course, the student will able to:
• choose the appropriate material for mechanical engineering applications
• find the optimal compromise between materials property, cost and ecological impact
• understand the most important concepts that allow for the tuning of mechanical and functional properties of materials
