Lärandemål

After a successful course, the student shall:

Kunskap och förståelse

• Fundamental understanding of microstructure development during solidification
• Knowledge about the effects of composition and cooling rate on microstructure
• Knowledge about how microstructure can be controlled and altered by trace level additions such as inoculation

Färdighet och förmåga

• Ability to calculate and discuss in details the formation of various solidification microstructures in relation to the phase diagram

Värderingsförmåga och förhållningssätt

• Ability to suggest methods to improve the microstructure and performance of cast metals

Innehåll

The formation of microstructure during solidification, mechanisms and impact of altered solidification conditions. The fundamental mechanisms of solidification including nucleation, primary phase growth, eutectics and peritectics. Furthermore, the mushy zone and its properties are discussed in relation to the formation of casting defects. Real-life examples of inoculation/grain refinement and modification of aluminium alloys and cast irons are described in detail.

The course includes the following elements:
1. Homogeneous and heterogeneous nucleation
2. Interface stability
3. Constitutional undercooling
4. Primary phase growth
5. Eutectics
6. Peritectics
7. Mushy zone characteristics and its importance for casting defects
8. Grain refinement and modification of aluminium
9. Cast iron - solidification characteristics, microstructures and control
