| Content | This course is designed as a two semester class and the topics reflect the contents covered in both semesters. Lectures and case studies encompass the following topics: Strategic Materials (where do raw materials come from, who owns them, who owns the IP and can they be substituted) Materials Selection (what is the optimal material (class) for a specific application) Materials systems (subdivisions include all classical materials classes) Processing Joining (assembly) Shaping Materials and process scaling (from nm to m and vice versa, from mg to tons) Sustainable materials manufacturing (cradle to cradle) Recycling (Energy recovery) After a general part of materials selection, critical materials and materials and design four parts consisting of polymers, metals, ceramics and coatings will be addressed. In the fall semester the focus is on the general part, polymers and alloy case studies in metals. The course is accompanied by hands-on analysis projects on everyday materials. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
