  3. 3. On the Machinability of High Performance Tool Steels

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Natalia Sandberg; Uppsala universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hot work tool steels; alloying composition; machinability; Materialvetenskap; Materials Science;

    Abstract : The continuous development of hot forming tool steels has resulted in steels with improved mechanical properties. A change in alloying composition, primarily a decreased silicon content, makes them tougher and more wear resistant at elevated temperatures. However, it is at the expense of their machinability.

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Seyyed Mohammad Hamed Hoseiny; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bainitic structure; Tool Life; Cutting Temperature; Cutting Force; Machinability; Microstructure; Tempered Martensite; Plastic 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.
