MATERIALS SCIENCE: METALS AND ALLOYS is the first course of the MATERIALS SCIENCE learning line. This course is the study of the properties of materials (metals, plastics, ceramics and composites) and how those properties are determined by a material’s composition and structure. In this course, you will study how to determine materials and learn about the structure of materials and how to select materials for certain applications. 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 material 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. The Materials Science courses provide insights 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.
In the first block of the semester, the relationships between materials and properties in connection with the production method are studied in Materials Science: Metals and Alloys. The lecture series discusses the structure of metals and the way in which metals plastically deform. Then, this knowledge is used to study different methods to increase the strength of metals and alloys. In block two and three of the semester, a deeper understanding of the behaviour of metallic materials is pursued, with a special emphasize on steel and aluminium alloys, phase transformations and various heat treatments. In addition, materials applied at relatively low and high temperatures are studied. Finally, the causes and effects of (high temperature) oxidation and corrosion are discussed.
