MATS1500 Materials Science and Engineering Course description

Physics is the science that looks at phenomena like mass, energy and motion. You are simply investigating why the world is the way it is and how we can explain it mathematically. Thus, physics is one of the support beams in engineering.

In this course, the student will learn about Newton's laws, and how to apply them mathematically to understand, for example, the conservation of energy, understand movement, speed and impact. In addition, the student will get an introduction to oscillations and electromagnetism.

An individual three-hour written exam under supervision.

The exam grade can be appealed.

In the event of a resit or rescheduled exam, an oral examination may be used instead. In case an oral exam is used, the examination result cannot be appealed.

No requirements over and above the admission requirements.

After completing the course, the student is expected to have achieved the following learning outcomes defined in terms of knowledge, skills and general competence:

Knowledge

The student can:

• Understand different levels of the materials substructure, and their influence in macroscopic properties and behavior: starting from the electronic structure of atoms, the different atomic bonding mechanisms, the atomic and ionic arrangements in materials and how the materials imperfections and their movement affect mechanical properties.
• Describe defects in crystalline materials, and explain grain boundary strengthening in polycrystalline materials.
• Explain driving forces for diffusion in materials, and the relevance of diffusion on different metal processing methods.
• Understand relevant properties of materials and the tests commonly performed to characterize these properties.
• Explain how liquid materials solidify via heterogeneous nucleation and describe different casting processes.
• Understand the various hardening mechanisms of metals: work hardening and annealing; solid-solution hardening; dispersion hardening; precipitation or age hardening.
• Understand phase diagrams as a means to identify the phases present in an alloy at different compositions and temperatures, and predict the microstructure of alloys resulting from eutectic and eutectoid phase transformations.
• Recognize and understand the main classifications, material structure, properties, processing and applications of other groups of materials beyond steels and aluminum alloys.
• Understand the basic fundamentals of electrochemistry and corrosion.

Skills

The student is capable of:

• Determining the electron configuration of different chemical elements. Using Miller indices to visualize crystalline metal structures and calculate lattice parameters. Inferring macroscopic material properties from crystallographic parameters.
• Calculating defect density, characterizing dislocations quantitatively, identifying slip systems and predicting its influence on mechanical properties.
• Calculating the diffusion coefficient, diffusion rate and diffusion composition profiles.
• Performing tensile testing of metallic materials and producing a test report in accordance with the applicable standard. Identifying stress, strain, elastic modulus, yield point and expressions of ductility and brittleness based on test curves, and measuring hardness.
• Predicting and characterizing fracture and creep. Outlining cold working and annealing processing methods to obtain target properties.
• Applying solidification principles for the characterization and design of iron castings, and determining solid solubility limits in alloys.
• Using phase diagrams to determine: phases present in an alloy, their composition and amounts; quantify dispersion hardening based on the analysis of eutectic and eutectoid phase transformations; design heat treatment methods used for hardening of metals, such as quench and temper to obtain martensite.
• Perform basic calculations related to electrochemistry/corrosion.

General competence

The student has acquired:

• A broad understanding of the different types of materials, where they are used, their properties and how they can be processed.
• The ability to make justified materials selection based on the criteria acquired in the course and with the eventual support of materials databases.
• An insight into the environmental, health-related, social and financial consequences of choices of materials, with an ethical and life cycle perspective.

Lectures and exercises.

No required coursework

The course addresses the engineering work that forms the basis of building a process plant. It includes calculations in process technology, preparation of drawings and selection of equipment and components. The field is theoretically demanding, but also requires practical sense.

A handheld calculator that cannot be used for wireless communication or to perform symbolic calculations. If the calculator’s internal memory can store data, the memory must be deleted before the exam. Random checks may be carried out.
