  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. Influence of matrix and alloying on the high cycle fatigue properties of compacted graphite iron for cylinder heads

    University essay from KTH/Hållfasthetslära

    Author : Erik From; [2020]
    Keywords : ;

    Abstract : Continued improvements in combustion processes, introduction of biofuels, decreasing fuel consumption and increasing specific power will inevitably lead to an increase of the combustion pressure, which can be accompanied with a temperature increase. This will increase the loading on many components and drives the development of materials more resistant to the harsh conditions close to the engine. READ MORE

  4. 3. Understanding the effect of temperature and time on Gamma prime coarsening for Nickel-base superalloy Haynes 282

    University essay from KTH/Materialvetenskap

    Author : Kevin Vattappara; [2019]
    Keywords : Haynes 282; gamma prime 𝛾′ ; Arc-heat treatment; COMSOL modelling; isothermal transformation; coarsening; Thermo-Calc simulations;

    Abstract : Haynes 282 is a gamma prime (𝛾′)-strengthened nickel base superalloy developed in 2005, exhibiting a good combination of high temperature properties and fabricability. Microstructural features such as 𝛾′ and carbides play an important role in deriving the mechanical properties of the alloy during heat treatment. READ MORE

  5. 4. Effect of temperature on mechanical response of austenitic materials

    University essay from Konstruktionsmaterial

    Author : Mattias Calmunger; [2011]
    Keywords : Dynamic strain aging; biomass power plant; austenitic stainless steel; nickel base alloy; stacking fault energy; twins;

    Abstract : Global increase in energy consumption and global warming require more energy production but less CO2emission. Increase in efficiency of energy production is an effective way for this purpose. This can be reached by increasing boiler temperature and pressure in a biomass power plant. READ MORE

  6. 5. Long Run Relationships between Base Metals, Gold and Oil

    University essay from Lunds universitet/Nationalekonomiska institutionen

    Author : Wenjia Duan; Garib Yusupov; [2010]
    Keywords : Commodities; Weak Exogeneity; VEC Granger Causality; Johansen Cointegration Test; Business and Economics;

    Abstract : This paper investigates the possible presence of long-run relationships (cointegration) among base metals and between base metals, Crude oil and Gold, using the Johansen multivariate approach and VEC Engle-Granger causality tests. The commodities used are seven base metals: Aluminum, Aluminum Alloy, Copper, Nickel, Zink, and Tin (from the London Metal Exchange), Crude oil and Gold. READ MORE
