1. Metal Expansion Penetration During Solidification of Grey Cast Iron
Sammanfattning : The meta! expansion penetration has been examined experimentally. The whole casting process was simulated using a commercial software, in order to investigate the solidification characteristics and the pore formation in the casting studied. LÄS MER
2. The mechanisms of metal expansion penetration during solidification of grey cast iron
Sammanfattning : The production of high quality castings requires the casting surface to be clean and free from defects. One type of defect often found is caused by metal penetration into the sand mould. LÄS MER
3. 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
4. Defect Formation during Solidification in Grey Iron Castings
Sammanfattning : The presence of defects is of major concern in the production of grey iron castings. Some defects are merely an aesthetic problem while others can be detrimental for the performance of the component. Among the several possible defects, shrinkage porosity is one of the more challenging to understand and avoid. LÄS MER
5. 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
