  4. 4. Microstructure model for Ti-6Al-4V used in simulation of additive manufacturing

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Corinne Charles Murgau; Corinne Charles; Högskolan Väst.; Luleå tekniska universitet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik; Titanium alloy; Ti-6Al-4V; Welding; Metal deposition; Additive manufacturing; Wire feed; Finite Element Method; Microstructure model; Johnson-Mehl-Avrami- Kolmogorov; Thermally driven; Material Mechanics; Materialmekanik;

    Sammanfattning : This thesis is devoted to microstructure modelling of Ti-6Al-4V. The microstructure and the mechanical properties of titanium alloys are highly dependent on the temperature history experienced by the material. The developed microstructure model accounts for thermaldriving forces and is applicable for general temperature histories. LÄS MER
