  1. 1. Nitrogen Without Oxygen : The effect of ferroalloys added after vacuum treatment on cleanliness of nitrogen-alloyed tool steel

    University essay from KTH/Materialvetenskap

    Author : Leo Nilsson Hultén; [2021]
    Keywords : Tool steel; Electro-Slag Remelting ESR; Nitrogen Alloying; Ferroalloys; Nonmetallic Inclusions NMI; Verktygsstål; Elektroslaggomsmältning ESR; Kvävelegering; Ferrolegeringar; Ickemetalliska Inneslutningar NMI;

    Abstract : Nitrogen-alloyed tool steel is made at Uddeholms AB by adding high-nitrogen ferroalloy after vacuum degassing where introduced impurities are hard to remove. In this thesis two types of high-nitrogen ferrochromium are compared, a solid version and a powder cored wire. READ MORE

  3. 2. Life and fracture in very high cycle fatigue of a high strength steel

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Daniel Karlsson; [2021]
    Keywords : Very high cycle fatigue; VHCF; Fractography; Fine granular area; FGA; High strength tool steel; Ultrasonic testing equipment;

    Abstract : Classical fatigue models teach that there is an intrinsic fatigue limit for steels, representing a level of stress that is too low for regular crack growth where every cyclic load propagates a fatigue crack through the material. Modern application with extreme lifetimes has shown that fatigue will still take place in steels with stress levels well below the expected fatigue limit. READ MORE

  4. 3. Turning of tool steel : Study on the effect of insert grade and entering angle on tool life

    University essay from KTH/Skolan för industriell teknik och management (ITM); KTH/Industriell produktion

    Author : Aravind Kartha; Shravan Subramanian; [2020]
    Keywords : Tool steel; machining; tool life; wear analysis; Verktygsstål; bearbetning; verktygslivslängd; förslitningsanalys;

    Abstract : PrimeTurning™ is a new turning technology, which consists of tools and programming method. By using this method, it has been demonstrated that higher material removal rates and flexibility in turning can be obtained. READ MORE

  5. 4. Process and microstructure development of a LPBF produced maraging steel

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Kenny Johansson; [2020]
    Keywords : Maraging steels; additive manufacturing; Laser Powder Bed Fusion; LPBF; additiv tillverkning; maråldringsstål; pulverbädd;

    Abstract : Additive manufacturing (AM) has the possibility of producing complex-shaped components which can not be produced by conventional manufacturing methods. This gives the opportunity for designers to freely think outside the design spectra which is otherwise limited by conventional manufacturing methods. READ MORE

  6. 5. Thermal fatigue and soldering experiments of additively manufactured hot work tool steels

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Henrik Andersson; [2018]
    Keywords : Additive manufacturing; 3D printing; Hot work tool steel; Thermal fatigue; heat checking; Die casting; Soldering; AISI H13; Additiv tillverkning; 3D printing; Varmarbetsstål; Termisk utmattning; Värmesprickor; Pressgjutning; Soldering; AISI H13;

    Abstract : Modern manufacturing processes are under a never ending evolvement. Lowered manufacturing costs, higher part quality, shorter lead times and lower environmental impact are some important drivers for this development. Aluminum die casting is an effective and attractive process when producing components for e.g. READ MORE
