  1. 1. Polishability of tool steels : Characterisation of high gloss polished tool steels

    Författare :Sabina Rebeggiani; Olaf Dambon; Högskolan i Halmstad; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tool steels; surface characterisation; polishability; 3D parameters; high gloss polishing; Surface engineering; Ytbehandlingsteknik;

    Sammanfattning : 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.

  4. 4. Estimating inclusion content in high performance steels

    Författare :Jens Ekengren; Jens Bergström; Christer Burman; Hans Nordberg; Karlstads universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials Engineering; Materialteknik;

    Sammanfattning : Non-metallic inclusions in steel pose a major problem for the fatigue resistance, especially regarding fatigue at very long lives corresponding to low cyclic stress levels, as well as being detrimental to material toughness and polishability.The largest inclusions are quite rare, which makes conventional detection methods timeconsuming if reliable results are to be obtained.

  5. 5. The Metallurgical Aspects of Machinability in Prehardened Mould Steels

    Författare :Seyyed Mohammad Hamed Hoseiny; Chalmers University of Technology; []
    Nyckelord :Bainitic structure; Tool Life; Cutting Temperature; Cutting Force; Machinability; Microstructure; Tempered Martensite; Plastic Mould Steels;

    Sammanfattning : 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.
