Materials for Mechanical Engineers

Abstract

This 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.

Objective

At 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
