1. Mechanical properties of semi-solid Al castings : Role of stirring
Sammanfattning : Aluminum castings have been widely used in the automotive industry to reduce the vehicle's weight. However, the existence of casting defects significantly limits its application. The most common and detrimental defects in aluminum castings are porosity and oxides. LÄS MER
2. Growth and Removal of Inclusions During Ladle Stirring
Sammanfattning : The growth and removal of inclusions in stirred ladles hasbeen studied. First, the importance of different growthmechanisms suggested in the literature were studied. Simulationresults from a fundamental model of an induction-stirred ladlehave been used as input in the calculations. LÄS MER
3. Study of the slag-metal interaction in ladle treatment
Sammanfattning : .... LÄS MER
4. Study of Non-metallic Inclusion in Alloy 825
Sammanfattning : It is well known that inclusions affect the properties of steels and alloys. Therefore, it is important to understand what type of inclusions that exist and how they behave and especially with a focus on large size inclusions. LÄS MER
5. Pores, inclusions and electromagnetic stirring : Topics from the continuous casting of steel
Sammanfattning : This thesis deals with two topics of relevance to the continuous casting of steel,in view of their importance as regards the quality of the final solidified structure.The first concerns the precipitation of gas pores and inclusions in the interden-dritic region of the solidifying metal.
