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

    Author : Noomi Linder; [2020]
    Keywords : Heat Treatments Isothermal Titanium Alloy Ti-6242 Ti6242 Ti-6Al-2Sn-4Zr-2Mo GKN;

    Abstract : The use and knowledge of additive manufacturing technologies are rapidly growing. It is crucial to understand the processing-structure-property relationship, which is highly discussed when trying to understand the science of a material. One commonly used material in aerospace applications is titanium alloy, lately Ti-6Al-2Sn-4Zr-2Mo (Ti-6242). READ MORE

    University essay from Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)

    Author : Prakruth Harish; [2020]
    Keywords : Ti 6242; LMD-w; Isothermal transformation diagrams; Microstructure of Ti 624;

    Abstract : The most widely used titanium alloy in the hot sections of a jet engine is Ti-6Al-2Sn-4Zr-2Mo (Ti-6242) and with the technological advancements additive manufacturing (AM) of Ti-6242 is of great interest. Although, there is not much published related to additively manufactured Ti-6242. READ MORE

  4. 18. Defining Black: Characterization of Soot Reactivity with Thermogravimetrical Methods : Definiera svart: Karaktärisering av sotreaktivitet med termogravimetriska metoder

    University essay from KTH/Tillämpad fysik

    Author : Adarsh Roy Choudhury; [2020]
    Keywords : Diesel Particulate Filter; Chemical Kinetics;

    Abstract : Exhaust emissions in a vehicle has to flow through an exhaust aftertreatment in a diesel vehicle. In a diesel engine, the exhaust emissions are treated with Diesel Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF), and Selective Catalytic Reduction (SCR). Every engine produces a different kind of soot depending on the drive cycle. READ MORE

    Abstract : This project investigates the influence of alloying elements, heat treatment and corrosion medium on the corrosion rates of three magnesium alloys Mg-5Zn, Mg0.27Ca, and Mg-0.27Ca-5Zn for use in bio-medical applications. READ MORE

  6. 20. An introduction to some ordinary differential equations governing stellar structures

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Yani di Giovanni; [2019]
    Keywords : Mathematics and Statistics;

    Abstract : The Lane-Emden equation is a non-linear differential equation governing the equilibrium of polytropic stationary self-gravitating, spherically symmetric star models; $${\frac {1}{\xi ^{2}}}{\frac {d}{d\xi }}\left({\xi ^{2}{\frac {d\theta }{d\xi }}}\right)+\theta ^{n}=0.$$ In the isothermal cases we have the Chandrasekhar equation: $${\frac {1}{\xi ^{2}}}{\frac {d}{d\xi }}\left({\xi ^{2}{\frac {d\psi}{d\xi }}}\right)-e^{-\psi}=0$$ After having derived these models, we will go through all cases for which analytic solutions are achievable.
