  2. 11. Growth and Characterization of Ti-Si-N Thin Films

    Author : Axel Flink; Lars Hultman; Paul Mayrhofer; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Analytical transmission electron microscopy; Arc; Sputtering; Hard coatings; Multilayer Cutting inserts; analytisk transmissionselektronmikroskopi; ytbeläggningar; skärande; bearbetning; Ti-Si-N; arcförångning; sputtring; Material physics with surface physics; Materialfysik med ytfysik;

    Abstract : Utvecklingen inom materialforskningen går mot att framställa avancerade material vilka är skräddarsydda för olika tillämpningar. Detta har medfört att det blir allt mer populärt att belägga ytor med ett eller flera tunna lager med syfte att förbättra materialegenskaperna. READ MORE

  4. 12. A study on Electron Beam Melted Ti-6Al-4V

    Author : Adnan Safdar; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ti-6Al-4V; Electron beam melting; Microstructures; Surface roughness; phase filed modelling.;

    Abstract : The work presented in this dissertation is concerned with the microstructures and surface roughness of test slabs of Ti-6Al-4V produced by one of powder based Additive Manufacturing (AM) technique namely electron beam melting (EBM). The effects of process parameters of a EBM system and geometry factors of a EBM build such as slabs’ thickness and height etc. READ MORE

    Abstract : Metastable (Ti,Si)N alloy and TiN/SiNx multilayer thin solid films as well as SiNx/TiN surfaces have been explored. Cubic Ti1-xSixN (0≤x≤0. READ MORE

  6. 14. Modelling microstructure evolution of weld deposited Ti-6Al-4V

    Author : Corinne Charles; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metal deposition; Ti-6Al-4V; microstructure modelling; titanium alloy; Finite Element Method; Johnson-Mehl-Avrami; RTMwD; Materials science; Teknisk materialvetenskap; Manufacturing and materials engineering; Produktions- och materialteknik; Material Mechanics;

    Abstract : The microstructure and consequently the mechanical properties of titanium alloys are highly dependent on the temperature history endured by the material. The manufacturing process of metal deposition induces repetitive cooling and heating in the material determining a specific microstructure. READ MORE

  7. 15. Control of Wear-Resistance Properties in Ti-added Hypereutectic High Chromium Cast Iron

    Author : Qiang Liu; Pär Jönsson; Keiji Nakajima; José Tinoco; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High Chromium Cast Iron; cooling rate; Ti addition; M7C3; TiC; carbides size distributions; volume fraction; heat treatment; microstructure; mechanical properties; wear resistance;

    Abstract : High chromium cast iron (HCCI) is considered as one of the most useful wear resistance materials and their usage are widely spread in industry. The wear resistance and mechanical properties of HCCI mainly depend on type, size, number, morphology of hard carbides and the matrix structure (γ or α). READ MORE
