Stelningsprocesser (Solidification Processing) 3 hp

Undervisningen bedrivs på engelska.

This course covers 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 are studied. 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 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
