  1. 1. Characteristics of cast aluminium-silicon alloys : microstructures and mechanical properties

    University dissertation from Institutionen för konstruktions- och produktionsteknik

    Author : Salem Seifeddine; Högskolan i Jönköping.; Högskolan i Jönköping.; Linköpings universitet.; Linköpings universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; Aluminium; microstructure; porosity; tensile properties; modelling.; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik; Aluminium; Mocrostructure; Porosity; Tensile properties; Modelling;

    Abstract : Applications of aluminium alloys are spreading in many industrial fields due to the excellent combination of castability, mechanical performance and lightness assured by such material. This project aims to establish a methodology in bringing the foundry process closer to the casting designer, and thereby leading to a more reliable and more optimised design. READ MORE

  2. 2. Tool steel for tool holder applications microstructure and mechanical properties

    University dissertation from Karlstad : Karlstad University

    Author : Anna Medvedeva; Karlstads universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; tool steel; tool holder; microstructure; mechanical properties; machinability;

    Abstract : Large improvements in cutting tool design and technology, including the application of advanced surface engineering treatments on the cemented carbide insert, have been achieved in the last decades to enhance tool performance. However, the problem of improving the tool body material is not adequately studied. READ MORE

  3. 3. Slip and fall risk on ice and snow : : identification, evaluation and prevention

    University dissertation from Karlstad : Karlstad University

    Author : Chuansi Gao; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Work Environment; Industriell produktionsmiljö; Winter sport; Gait; Dynamic balance; EMG; Experience; Usability; Coefficient of friction; Footwear; Systems model; Ergonomics; Safety; Accident; Risk; Ice and snow; Slip and fall;

    Abstract : Slip and fall accidents and associated injuries on ice and snow are prevalent among outdoor workers and the general public in winter in many regions of the world. To understand and tackle this multi-factorial problem, a multidisciplinary approach was used to identify and evaluate slip and fall risks, and to propose recommendations for prevention of slips and falls on icy and snowy surfaces.

  4. 4. Environmentally adapted lubricants properties and performance

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Anders Pettersson; Luleå tekniska universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Abstract : The lubricants of the future have to be more environmentally adapted, show a higher level of performance, and give a lower total life cycle cost (LCC) than the lubricants that are used today. One way to be able to produce, choose and formulate these lubricants is to have good knowledge about the properties of the base fluids and their additive response. READ MORE

  5. 5. Footwear for cold environments. Thermal properties, performance and testing

    University dissertation from Luleå University of Technology, Dept. of Human Work Sciences, Div. of Industrial Ergonomics / Arbetslivsinstitutet, Programme for Respiratory Health and Climate

    Author : Kalev Kuklane; [1999]

    Abstract : Abstract in Uncoded languages Praegune kaitsejalatsite testimise standard (EN 344) kontrollib soojapidavuslikke omadusi vaid jalatsi ühes punktis, mõõtes temperatuuri muutust. Meetod, mis kasutab termilist jala mudelit, võimaldab mõõta jalatsi soojaisolatsiooni üheaegselt erinevates piirkondades ning ühtlasi ka jalatsi kui terviku soojaisolatsiooni. READ MORE
