Cursusdoelen
This course will be offered during the fourth quartile.

After the course the student is able to...
  1. Derive phase diagrams on the basis of thermodynamic data of simplified binary (metal) alloys.
  2. Explain the microstructure of an alloy or a polymer after solidification or solid state transformation under equilibrium or non-equilibrium conditions on the basis of phase diagrams and kinetics data.
  3. Determine the influence of the processing conditions on the material microstructure and associated mechanical properties of the material.
  4. Describe the defining differences between crystalline and amorphous solids and analyze typical thermodynamic measurement results obtained on glasses.         
  5. Comprehend and present a relevant subject on phase transformations in manufacturing in a clear and structured manner both in an oral presentation given in the form of a lecture as in the form of a short reader.

Content
Phase transformations in manufacturing provides deeper understanding of the thermodynamics and kinetics of phase transformations in metals, alloys, polymers and thermoplastic composites during moulding/forming processes. The processes include typical manufacturing processes for metals and alloys such as casting, forging and welding, for polymers such as extrusion and injection moulding, and for fiber reinforced polymers, such as resin transfer moulding, stamp forming and fiber placement. In fact, all processes where the resulting microstructure of the material is influenced by heat and/or mechanical deformation may be considered. The development of the microstructure depends on the process conditions and is key to understand the material properties and to find new routes to property and microstructure optimization. In this way product performance can be safeguarded or enhanced.
Understanding the influence of heat and deformation on the interrelation between process, product and material properties forms the main course goal.
 
Structure
The course consists of two parts. In the first part lectures are given to provide the background in thermodynamics of metal alloys and solidification. These lectures treat the origin of phase diagrams which are vital to understanding of the behavior of most engineering materials. They also explain the phenomena occurring during solidification of materials and solid state phase transformations. A special emphasis is put on the conditions governing the formation of amorphous solids, i.e., materials without a crystalline order. Subsequently, a number of lectures is devoted to polymers and to composite materials. The lectures on polymers treat the kinematics of structure formation via crystallization and the requirements for certain phase transformations. The lectures on composites discuss the implications of phase transformations on the manufacturing and the (mechanical) performance of fiber reinforced polymer parts.
 
In the second part the student selects a typical manufacturing process and/or phenomenon (assignment). The student will prepare a 30 minute lecture to be presented in front of the colleague students. A list of possible subjects is supplied, but students are encouraged to propose relevant subjects themselves.
 
During the lecture the student will discuss the interrelations between microstructure, material and the production process. For example, the student will explain the metallurgical background of the selected process/phenomenon in light of the provided lectures on thermodynamics and solidification. Furthermore, the student will provide a short reader supporting the lecture. A similar approach holds for a topic on polymers and/or composite materials.
 
Support

During the second part the students receives feedback from the instructor with the preparation of the lecture and the reader. As soon as the lecture and the reader are of sufficient quality (pre-lecture check by instructor), the student is given the opportunity to give the 30 minute lecture. The work should be presented at the level of a master student having followed the course. During the lecture the other participating students are encouraged to ask (in-depth) questions.
