1. 1. Design and Development of Light Weight High Entropy Alloys

   Master-uppsats, Högskolan i Jönköping/JTH, Material och tillverkning

   Författare :Akash Avinash Gondhalekar; [2019]
   Nyckelord :High Entropy Alloys; CCAs; Solid Solutions; Intermetallic Compounds; Thermodynamic; Multicomponent; Microstructure; Mechanical Properties;

   Sammanfattning : The main aim of this thesis was to design and develop new Aluminium based compositionally complex alloys (CCAs) using the high entropy alloy (HEA) concept, and to understand their evolution of microstructures during casting and also after the secondary process which is heat-treatment, and finally to evaluate their subsequent mechanical properties. Prior to the development of alloys, a computational technique ThermoCalc was used which helped in understanding the phase formation in various results. LÄS MER

3. 2. Intermetallic Compound Formation in Ni-Ti-Fe Powder Mixtures

   Master-uppsats, Lunds universitet/Materialteknik

   Författare :Tea Bertilsson; [2018]
   Nyckelord :Phase Evolution; Ni-Ti-Fe System; Intermetallics; Powder Metallurgy; Reactive Sintering; DSC; SEM; EDS; XRD; Technology and Engineering;

   Sammanfattning : The Ni-Ti system has a broad range of applications, in areas as diverse as biomedicine and robotics. This is in large due to the NiTi intermetallic compound, which exhibits the shape memory effect. In addition to this property, the intermetallic compound is also biocompatible, has good mechanical properties and good corrosion resistance. LÄS MER

4. 3. Synthesis and characterizationof rare earth free magnetic materialsfor permanent magnet applications

   Uppsats för yrkesexamina på grundnivå, Institutionen för kemi - Ångström

   Författare :Johan Cedervall; [2013]
   Nyckelord :permanent magnet; magnetism; intermetallic compounds; iron alloys; permanentmagneter; magnetism; intermetalliska föreningar; järnlegeringar;

   Sammanfattning : In this thesis the compounds Fe5SiB2 and Fe5PB2 have beensynthesized via high temperature synthesis, including arc melting anddrop synthesis. The structure for both compounds are of Cr5B3 typewith the space group I4/mcm. The cell parameters were refined toa = 5.5533 Å and c = 10. LÄS MER

5. 4. Mechanical Reliability of Aged Lead-­Free Solders

   Kandidat-uppsats, KTH/Materialvetenskap

   Författare :Susanne Lewin; [2012]
   Nyckelord :Solder Joints; Lead-free; Mechanical Reliability;

   Sammanfattning : The usage of lead-­free solder joints in electronic packaging is of greatest concern to the electronic industry due to the health and environmental hazards arising with the use of lead. As a consequence, lead is legally prohibited in the European Union and the industry is aiming to produce lead-free products. LÄS MER

7. 5. Hydrogen absorption/desorption properties of the Sc(AlxNi1-x)2 system

   Uppsats för yrkesexamina på avancerad nivå, Oorganisk kemi

   Författare :Jonas Ångström; [2011]
   Nyckelord :hydrogen storage; Laves phases; Ni-MH batteries; intermetallic compounds; alloy; alloys; Nickel; Hydrogen; Scandium; Sc; Ni; Aluminium; Aluminum; Al; Nickel metal hydride batteries; Laves phase; vätelagrning; Lavesfaser; Ni-MH batteri; intermetalliska föreningar; legering; legeringar; nickel; väte; skandium; aluminium; Lavesfas;

   Sammanfattning : Sc(AlxNi1-x)2 is a pseudobinary C14 Laves phase and a potential interstitial hydrogen storage material or anode in a Ni-MH battery. A previous study showed that Sc1Al1Ni1 can store hydrogen reversibly; both interstitially and trough decomposition into ScH2 and AlNi. LÄS MER
