21. A Study on the Population and Chemical Development of Non-Metallic Inclusions in the Tool-Steel Making Process
Sammanfattning : The present work was to study the population and chemicalcharacterization of the inclusions at different steps of thetool steel making process based on industrial trialexperiments. The inclusion populations were found to increasewith ladle age (number of heats ladle being used) beforealuminium deoxidation and before casting. LÄS MER
22. Characteristics of cast aluminium-silicon alloys : microstructures and mechanical properties
Sammanfattning : Applications of aluminium alloys are spreading in many industrial fields due to the excellent combination of castability, mechanical performance and lightness assured by such material. This project aims to establish a methodology in bringing the foundry process closer to the casting designer, and thereby leading to a more reliable and more optimised design. LÄS MER
23. On microstructure formation and mechanical properties in grey cast iron
Sammanfattning : A major user of cast components is the automotive industry, where the functionality of the components is related to environmental demands. Internal combustion engines are constantly being improved to emit less pollution. A vital part in this development is to increase the material properties of engine components during their life cycle.

24. On the Characterization and Generation of Flow Marks on Polymeric Surfaces
Sammanfattning : Polymer-based materials are widely used in the automotive industry for producing vehicle parts, for instance car bumpers, dash boards etc. A common manufacturing process for such components is injection moulding. LÄS MER
25. Flow-induced Surface Defects and Ageing Behaviour of Injection-moulded Polymers
Sammanfattning : Injection moulding is one of the most commonly used manufacturing methods for the production of polymer-based components such as car bumpers and other automotive details. The surface appearance of these products is of great importance since it is directly connected to the perceived quality. LÄS MER
