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

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Corinne Charles Murgau; Corinne Charles; Högskolan Väst.; Luleå tekniska universitet.; [2016]
    Keywords : 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;

    Abstract : 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. READ MORE

  2. 2. Towards the Improvement of Salt Extraction from Lake Katwe Raw Materials in Uganda

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Hillary Kasedde; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lake Katwe; salt extraction; brine; evaporites; saltpan; characterization; evaporation - crystallization; solubility; Pitzer ’s ion - interaction model; PHREEQC software; dissolution kinetics; Avrami model.;

    Abstract : Uganda is well endowed with economic quantities of mineral salts present in the interstitial brines and evaporite deposits of Lake Katwe, a closed (endorheic) saline lake located in the western branch of the great East African rift valley. Currently, rudimentally and artisanal methods continue to be used for salt extraction from the lake raw materials. READ MORE

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

    University dissertation from Luleå : Luleå University of Technology

    Author : Corinne Charles; Högskolan Väst.; Luleå tekniska universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; Manufacturing and materials engineering; Produktions- och materialteknik; metal deposition; Ti-6Al-4V; microstructure modelling; titanium alloy; Finite Element Method; Johnson-Mehl-Avrami; RTMwD; Material Mechanics; Materialmekanik;

    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

  4. 4. Investigations on the Physico-Chemical Phenomena during Induration of a Magnetite Pellet

    University dissertation from Luleå : Luleå University of Technology

    Author : T. K. Sandeep Kumar; Luleå tekniska universitet.; [2018]

    Abstract : In the era of globalization with increasing environmental awareness, sustainable utilization of the available resources is a necessity; iron ores are no exception. Pelletization, being one of the increasingly practiced agglomeration techniques for the iron ore fines as well as other solid wastes from steel plants. READ MORE

  5. 5. Cementitious properties of steelmaking slags

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Daniel Adolfsson; Luleå tekniska universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : The present study is directed towards the use of steelmaking slags as raw material for sulphoaluminate belite cement (SAB). Another important objective was to characterise the cementitious properties of phases in ladle furnace slag (LFS) specifically the calcium aluminates. READ MORE
