1. Compacted graphite iron : On solidification phenomena related to shrinkage defects
Sammanfattning : An improved understanding of solidification of compacted graphite iron (CGI) is necessary to predict shrinkage related casting defects. Spheroidal graphite is not only found in ductile iron (SGI) but usually also in CGI, but its characteristics and role in this material is less understood. LÄS MER
2. Phase-field Simulation of Dendritic Solidification
Sammanfattning : .... LÄS MER
3. Study of solidification and volume change in lamellar cast iron with respect to defect formation mechanisms
Sammanfattning : Lamellar cast iron is a very important technical alloy and the most used material in the casting production, and especially in the automotive industry which is the major consumer. Beside the many great properties, it is inclined to form casting defects of which some can be prevented, and some may be repaired subsequently. LÄS MER
4. On the solidification of compacted and spheroidal graphite irons
Sammanfattning : A good understanding of the solidification process of a cast material is essential to understand how the combination of alloy composition and the casting process variables combines into the solid cast component and its performance. The wrong combination may result in poor performance or casting defects. LÄS MER
5. Morphological characterization of primary austenite in cast iron
Sammanfattning : Automotive industry products portfolio includes a wide variety of complex‐shaped cast iron products, such as truck engine components, that need to withstand a constant trend of higher demands, especially urged by stricter environmental regulations on emissions. Combined with this continued demand on properties improvement, cast iron industry faces a process problem related to the lack of understanding of solidification and mechanisms behind defect formation.
