  1. 21. Fracture behaviour and related microstructures of tool steels parted-off at high rates of strain

    Author : Kristina Ryttberg; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-velocity parting-off; adiabatic cutting; high strain-rate deformation; TEM; steel; adiabatic shear band;

    Abstract : Increasing steel prices and environmental aspects have put forward the demand to reduce material consumption in manufacturing industry and near-net-shape manufacturing techniques have thus become increasingly important. High-velocity parting-off, or adiabatic cutting, has shown to result in very low material waste as well as narrow dimensional tolerances of parted-off samples. READ MORE

  2. 22. Microstructure and mechanical properties of a 5 wt.% Cr cold work tool steel Influence of heat treatment procedure

    University dissertation from Trollhättan : University West

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cold work tool steel; Heat treatment; Microstructural characterisation; Mechanical properties; Retained austenite; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : The demand for Advanced High Strength Steel (AHSS) in the automotive industry is increasing day by day. It is mainly motivated by the fact that AHSS can be used as thin sheets while having high strengths. READ MORE

  3. 23. Process integration in the steel industry possibilities to analyse energy use and environmental impacts for an integrated steel mill

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Mikael Larsson; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : There is a growing awareness of serious problems associated with the use of energy. These problems include local and global environmental degradation associated with energy use and depletion of resources. READ MORE

  4. 24. High Pressure Jet Assistance in Steel Turning

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Patrik Dahlman; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Jet Assistance; Tool Life; Chip Control; Turning; Ultra High Pressure Cooling; Jet Momentum;

    Abstract : Steel turning is one of the most common industrial processes today. It is a very old process, where a lot of improvements and optimisations have been done throughout history. But, the struggle for further cost reductions pushes the process development into new areas. READ MORE

  5. 25. Very high cycle fatigue of tool steels

    University dissertation from Karlstad : Karlstad University

    Author : Vitaliy Kazymyrovych; Karlstads universitet.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fatigue; crack growth; ultrasonic testing; tool steels; inclusions; Materialteknik; Materials Engineering;

    Abstract : An increasing number of engineering components are expected to have fatigue life in the range of 107 - 1010 load cycles. Some examples of such components are found in airplanes, automobiles and high speed trains. READ MORE
