  1. 1. Nanoindentation characterization of high chromium white cast iron for assessment of machining performance

    Författare :Ling Chen; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanoindentation; FEM; Characterization; High chromium cast iron; Machining; Grid nanoindentation;

    Sammanfattning : As modern production moves towards higher efficiency and cost effectiveness, machining difficult-to-cut materials becomes an increasing challenge. Quickly and reliably characterizing the properties of materials could significantly improve the performance of machining processes in terms of their efficiency and production cost. LÄS MER

  3. 2. Thin film growth and characterization of Ti-(Si,Ge)-C compounds

    Författare :Per Eklund; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This thesis describes growth by de magnetron sputtering of thin film Ti-Si-C and Ti-Ge-C materials, with an emphasis on the deposition conditions for nanocomposite and epitaxial growth at low and high temperature processing, respectively. In the Ti-Si-C materials system, I have synthesized nanocomposite thin films from a Ti3SiC2 compound target in an Ar discharge on Si(100), Al2O3(0001), and Al substrates at low substrate temperature (300 oC and below).

  4. 3. Micro-mechanical characterization and modeling of paper and paperboard

    Författare :August Brandberg; Artem Kulachenko; Sören Östlund; Carl Dahlberg; Rami Mansour; Ron Peerlings; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Fiber networks made of cellulose fibers from trees are used as information carriers (paper) and as packaging (paperboard). This thesis investigates the mechanical performance of paper and paperboard via micro-mechanical modeling and presents new methods for the mechanical characterization of the micro scale, necessary in such models.
