    Sammanfattning : The protein folding problem is addressed focussing on the hydro- phobicity patterns in the amino acid sequences and structures. Both real and model proteins are investigated. The hydrophobicity pattern of real proteins is probed in two ways. First, it is asked which binary pattern is most conserved within groups of related proteins. LÄS MER

    Sammanfattning : This thesis reports on quantitative investigations of microstructural changes, mainly precipitation reactions, occurring during heat treatment, ageing and creep of 9-12% chromium steels. Several alloys with varying composition have been investigated. LÄS MER

  4. 3. Mechanical Properties, Microstructures and Defects of Tool Steels Fabricated by Additive Manufacturing

    Författare :Yuan Miwen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Carbides; Post heat treatment; Directed energy deposition; Softening resistance; Pores; Laser beam powder bed fusion; Solidification cracking; Tool steels;

    Sammanfattning : Additive Manufacturing (AM) has been gaining significant interest in the manufacturing of metallic materials in the recent years. From a techno-commercial standpoint, tooling is one of the areas with low production volumes but very high demands on part performance and complexity in design, all of which are characteristic for metal AM.
