  1. 1. Microstructural design and optimization of Nickel-based superalloys for gas turbines

    University essay from KTH/Materialvetenskap

    Author : Anirudh Vasishta; [2023]
    Keywords : Nickel- based superalloys; gamma prime γ′ size calculations; Nickelbaserade superlegeringar; gamma prime γ′ storleksberäkningar;

    Abstract : One of the main sources of energy in this modern world is the gas turbine.  They reach extremely high working temperatures at peak capacity and hence require materials that can withstand the same. READ MORE

  3. 2. 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

  4. 3. Design of cemented carbide with Ni-based superalloy binder strengthened with y’-Ni3Al precipitates

    University essay from KTH/Materialvetenskap

    Author : Oscar Edholm; [2018]
    Keywords : Cemented Carbide; Super alloy; Ni-alloy; Ni-Super alloy; Superalloy; Ni3Al; NiAl; Gamma Prime; Gamma; Precipitates; Ni3Al Precipitates; Master Alloy; Liquid Phase Sintering; Cementerad karbid; Hårdmetall; Superlegering; Ni-legering; Ni-Superlegering; Superalloy; Ni3Al; NiAl; Gamma Prim; Gamma; Precipitates; Ni3Al Precipitates; Mästerlegering; Utfällning;

    Abstract : Replacement of cobalt in cemented carbides has gained in attention recently because threats of regulations due to health issues (cancerogenic effect), increased demand from the electric vehicle industry and the questionable extraction from countries like Democratic Republic of Congo. In this report the use of Ni-based binder as an alternative binder for cemented carbides has been explored. READ MORE

  5. 4. Predicting Customer Lifetime Value : Understanding its accuracy and drivers from a frequent flyer program perspective

    University essay from Linköpings universitet/Institutionen för ekonomisk och industriell utveckling

    Author : Kevin Do Ruibin; Tobias Vintilescu Borglöv; [2018]
    Keywords : ;

    Abstract : Each individual customer relationship represents a valuable asset to the firm. Loyalty programs serve as one of the key activities in managing these relationships and the well-developed frequent flyer programs in the airline industry is a prime example of this. READ MORE

  6. 5. An introduction to the Riemann hypothesis

    University essay from KTH/Matematik (Inst.)

    Author : Alexander Bielik; [2014]
    Keywords : ;

    Abstract : This paper exhibits the intertwinement between the prime numbers and the zeros of the Riemann zeta function, drawing upon existing literature by Davenport, Ahlfors, et al. We begin with the meromorphic continuation of the Riemann zeta function ζ and the gamma function Γ . READ MORE
