1. Metal Expansion Penetration During Solidification of Grey Cast Iron
Abstract : 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. READ MORE

2. The mechanisms of metal expansion penetration during solidification of grey cast iron
Abstract : 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. READ MORE

3. Properties and applications of materials based on graphite oxide
Abstract : Graphite oxide (GO) is a hydrophilic, layered material prepared by oxidation of graphite. In the first part of this thesis, we studied materials produced from GO by intercalation and functionalization. The second part of the thesis was focused on supercapacitor applications of high surface area carbons prepared from GO using chemical activation. READ MORE

4. A study on the Submerged Entry Nozzels (SEN) respecting clogging and decarburization
Abstract : The submerged entry nozzle (SEN) has been used to transport the molten steel from tundish to the mould. The main purpose of the SEN usage is both to prevent oxygen and nitrogen pick-up by molten steel and to achieve the desired flow condition in the mould. READ MORE
