1. Polishability of tool steels : Characterisation of high gloss polished tool steels
Abstract : The manufacturing of plastic components, like a majority of other mass produced discrete parts, require well designed dies and moulds. Complex geometries and increasing demands on final surface appearance, which is strongly connected to the quality impression, are pushing for high demands on mould-makers and polishers as well as steel producers.

2. The Metallurgical Aspects of Machinability in Prehardened Mould Steels
Abstract : High economical efficiency obtained by utilizing prehardened mould steels in plastic mould making has increased the usage of these types of steels to a great extent. Generally, prehardened mould steels are applied for large moulds and moulds for moderate production runs, and one of the advantages of using this type of steel is that no heat treatment is necessary for putting the mould in use.

5. On Peritectic Reactions and Transformations and Hot Forming of Cast Structures
Abstract : This thesis deals with peritectic reactions and transformations that occur during the solidification of many alloys. Peritectics are believed to be a major cause of crack-formation in many steels, thus, good knowledge of the mechanisms by which these phenomena occur is essential for preventing such defects.
