  2. 2. Bracing of steel bridges during construction; theory, full-scale tests and simulations

    University dissertation from Stockholm : Materialvetenskap

    Author : Hassan Mehri; Lunds universitet.; Lund University.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bracing; steel-concrete composite; steel; bridge; test; construction; laboratory; experiment; experimental; theory;

    Abstract : Popular Abstract in English Bracings are structural components that assure the stability of the load bearing structures is maintained so as a desired level of load-carrying capacity of them is achieved. The present study as a whole involves investigations of either the temporary or permanent bracings that are often required during the construction phase of steel bridges. READ MORE

  3. 3. A Study of Slag/Metal Equilibrium and Inclusion Characteristics during Ladle Treatment and after Ingot Casting

    University dissertation from Stockholm : KTH

    Author : Hamid Doostmohammadi; KTH.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inclusions; thermodynamics; ladle treatment; vacuum; tool steel; bearing steel; slag; equilibrium; slag carryover; oxides; sulfides.; TECHNOLOGY Chemical engineering Metallurgical process and manufacturing engineering Metallurgical process engineering; TEKNIKVETENSKAP Kemiteknik Metallurgisk process- och produktionsteknik Metallurgisk processteknik;

    Abstract : Today, there is a high demand on clean steel for high performance materialproperties. Thus, steel producers try to deliver a steel product with the highestquality and cleanliness to the market. The number of parameters that affect thesteel cleanliness may vary depending on the required material properties of thefinal product. READ MORE

  4. 4. Mechanical behaviour of a roller bearing steel Strength differential effect, low temperature creep and propagation of short cracks

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Irene Linares Arregui; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Fatigue cracks in bearings either initiate from the surface or from an inclusion below the rolling contact surface. Then, short cracks start to propagate. Short crack grow at considerably faster rates than long cracks subjected to a nominally equivalent stress intensity factor range. READ MORE

  5. 5. Hard Turning of Bearing Steels. Controlling residual stress and improving fatigue life

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Michael Jacobson; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; x-ray diffraction; bearing steel; residual stress; fatigue life; cutting conditions; hard turning;

    Abstract : There are many different precision mechanical components such as bearings, fuel injectors, gears and hydraulic components, which are made of hardened steels, and have to be machined to a high degree of precision. Traditionally these components are being ground. READ MORE
