  1. 1. Optimization of the process-route of a Nickel-base alloy : Investigation of Sigma-phase precipitation in heat treatment

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

    Author : Felix Andersson; [2023]
    Keywords : Sigma-phase; austenitic stainless steel; Nickel-base alloy; heat treatment; Sigmafas; austenitiskt rostfritt stål; Nickelbas legering; värmebehandling;

    Abstract : The focus of this master’s thesis is on the heat treatment of Ni-base alloys, specifically the risk of intermetallic σ-phases during different stages of heat treatment. The alloy studied is Sanicro®28, a super-austenitic stainless steel produced by Alleima AB. READ MORE

  3. 2. Investigation of high temperature stability of additive manufactured austenitic stainless steels for space applications

    University essay from Luleå tekniska universitet/Materialvetenskap

    Author : Belén Alonso Rancurel; [2023]
    Keywords : austenitic stainless steel; additive manufacturing; high temperature corrosion; high temperature stability;

    Abstract : Additive manufacturing (AM) techniques are being studied for their application in the aerospace industry. Numerous benefits come from the already in shape final piece, which needs reduced amount of prime material for its production and can have its shape numerically optimized for weight reduction.

  4. 3. High temperature corrosion in exhaust application for heavy-duty trucks

    University essay from KTH/Materialvetenskap

    Author : Alice Moya; [2019]
    Keywords : high temperature corrosion; austenitic steel; cast iron; cast steel; oxidation; exhaust gas; engine; heavy-duty trucks;

    Abstract : Increasing awareness of environmental protection has made both governments and the industry aim for lowering carbon dioxide emissions. For the transport industry this means increasing engine efficiency, replacing fossil fuels with bio-based fuels or full electrification. READ MORE

  5. 4. An Investigation of Stainless Steels for Long-term Use in Liquid Sodium at up to 700°C

    University essay from KTH/Materialvetenskap

    Author : Clara Bubenko; Karl Magnil; Melker Olofsson; [2019]
    Keywords : ;

    Abstract : The Swedish company Azelio has developed a high-efficient Stirling engine which is powered by solar energy. Since the access of solar power is limited to day-time, Azelio has also developed their own Thermal Energy Storage (TES), which collects and stores solar energy and thereby provides the engine with energy also during night-time.

  6. 5. Optimization of Rare Earth Metals (REM) addition in high temperature stainless steel grade 253MA.

    University essay from KTH/Materialvetenskap

    Author : Bharath Vasudev Rangavittal; [2019]
    Keywords : REM addition; non-metallic inclusion; oxidation; austenitic; optimization;

    Abstract : The focus of this thesis work is to optimize rare earth metal (REM) addition in Therma 253MA, an austenitic stainless-steel grade in order to get a good trade-off between oxidation resistance property and the amount of big REM inclusions formed. Big REM inclusions are detrimental to material properties and REM is required to be dissolved in the matrix for improving the oxidation resistance. READ MORE
