1. 21. Deformation-Induced Martensitic Transformation and Mechanical Properties of Duplex and Austenitic Stainless Steels : A Synchrotron X-Ray Diffraction Study

   University essay from KTH/Metallografi

   Author : Sen Lin; [2017]
   Keywords : Synchrotron radiation; High energy X-ray diffraction; In situ tensile loading; TRIP steel; Martensite phase transformation;

   Abstract : Metastable austenitic and duplex stainless steels are widely used materials in industrial anddomestic applications, owing to their attractive characteristics such as good corrosion resistanceand favorable mechanical properties. Both types of steel experience enhanced mechanicalproperties during plastic deformation due to the formation of the martensite phase from theparent austenite phase, this is called deformation-induced martensitic transformation (DIMT).

3. 22. Development of aluminium-silicon alloys with improved properties at elevated temperature

   University essay from Högskolan i Jönköping/JTH, Material och tillverkning

   Author : Toni Bogdanoff; [2017]
   Keywords : Al-Si alloy; Nickel; Cobalt; Elevated temperature properties; Microstructure;

   Abstract : Aluminium-silicon alloys have gained increasing market share in the automotive and aerospace industry because of increased environmental demands. These alloys have a high strength-to-weight ratio, good corrosion resistance, castability and recycling potential. READ MORE

4. 23. Electrical connection for aluminium conductors in automotive applications : Prestudy of available solutions for electrical connection methods of aluminium cables

   University essay from KTH/Materialvetenskap

   Author : Emilia Hamedi; [2017]
   Keywords : Connector; electrical contact; termination; aluminium conductor;

   Abstract : Due to increasing weight of electrical component and wiring harnesses in a vehicle contrary to the demand of light constructed vehicles as well as the constantly increasing and fluctuating price of copper compared to aluminium’s stable and far lower price, the use of aluminium conductors as an alternative have been promoted.  This thesis work lay theoretical research of the available methods used for electrical connection of aluminium conductors in order to increase the knowledge about the available termination techniques.

5. 24. Corrosion protection of powder coatings : Testing the barrier properties and adhesion of powder coating on aluminum for predicting corrosion protection by Electrochemical Impedance Spectroscopy

   University essay from Högskolan i Jönköping/JTH, Produktutveckling

   Author : Björn Persson; johanna Svensk; [2017]
   Keywords : Electrochemical Impedance Spectroscopy; EIS; corrosion protection; powder coating; barrier properties; adhesion; aluminium;

   Abstract : The choice of corrosion protection system depends on the environment and needed lifetime for the product. The right corrosion protection should be selected in a sustainable point of view, since a well-selected coating system can reduce the environmental and economical impact, by using less and better material.

6. 25. Evaluation of Heat Treatments for the Nickel-Based Superalloy Haynes® 282® Manufactured by Selective Laser Melting : A Study Based on Microstructural Examinations and Mechanical Testing

   University essay from Linköpings universitet/Konstruktionsmaterial

   Author : Adam Selldén; [2017]
   Keywords : ;

   Abstract : Nickel-based superalloys have a wide range of applications, mainly in gas turbines for power generation and aircraft propulsion. They are superior to competing alloys in maintaining excellent mechanical properties for extended durations at extreme temperatures and loads, all while resisting corrosion and oxidation. READ MORE
