Intended Learning Outcomes (ILO)
On completion of the course, the student should
Knowledge and understanding
- basic understanding for how a microstructure is formed in a material during solidification
- knowledge about melt treatment and their influence on microstructure and properties
- knowledge about the solidification of metals the phenomena which influence the properties of products
- knowledge about how the microstructure and heat treatment influence the properties of cast metals
Skills and abilities
- ability to use the phase diagram to calculate and discuss in detail the formation of microstructure during solidification and phase transformations which occur
Judgement and approach
- able to suggest potential methods to improve the properties of cast materials.
Microstructure of cast metals, how it forms and its influence on mechanical and physical properties. Focus is on cast and heat treated metals. The course consists of two parts, where the first part covers process knowledge through the theory of solidification, phase diagram, and the solid state phase transformations which occur during cooling and during heat treatment. Melting and process control. The other past covers material properties and how these can be influenced by different treatments. Understanding of the relationship between process-microstructure-properties is core in this part of the course. Thus, the first part of the course is about the basic science of the formation of cast microstructures and the second half about the relationship between structure, properties and heat treatment.
The course includes the following parts:
- Overview of cast metals and phase diagrams
- Solidification mechanisms and microstructure formation, and their influence on mechanical and physical properties in cast metals
- Melt metallurgy, modification and nucleation and their influence on the solidification path
- Heat treatment
- The process-microstructure-property relationship
- Mechanical properties, static and dynamic
- Thermodynamic calculations
