1. 1. Magnetic properties of a martensitic stainless steel powder : Investigation of magnetic properties for a metallic powder with different sizes and its possible correlation to flow properties

   Kandidat-uppsats, KTH/Materialvetenskap

   Författare :Carl Back; Saga Grevarp; Arthur Pollet; [2023]
   Nyckelord :;

   Sammanfattning : For metal powders, flow properties are important. If the powder does not move properly, it can result in problems with the final product in additive manufacturing. Some of the products created with this manufacturing method are complex and used for important purposes such as medical devices and aerospace. LÄS MER

3. 2. Paleomagnetic and Thermomagnetic Studies on Rock Samples from COSC - 1 Drilling Project

   Master-uppsats, Uppsala universitet/Geofysik

   Författare :Wanyi Li; [2022]
   Nyckelord :Scandinavian Caledonides; remanent magnetization; AF demagnetization; temperature dependent magnetic susceptibility; Skandinaviska Kaledoniderna; remanent magnetism; växelfältsavmagnetisering; temperaturberoende av magnetisk susceptibilitet;

   Sammanfattning : The COSC-1 borehole located in the Lower Seve nappe of the Central Scandinavian Caledonides is intended to study the tectonic evolution of the Paleozoic orogen. The drilling project reached a depth of 2495.8m and obtained samples from different lithologal units of mica schist, amphibolite, gneiss, and mylonitic gneisses. LÄS MER

4. 3. Simulations of stray radiation in the European XFEL undulators with the Geant4 toolkit

   Kandidat-uppsats, Stockholms universitet/Fysikum

   Författare :Guillermo Lopez Basurco; [2022]
   Nyckelord :Geant4; Monte Carlo simulations; XFEL undulators; gamma radiation flux;

   Sammanfattning : The European XFEL is an X-ray free electron laser research facility that generates ultrashort, high intensity flashes. Three SASE undulator systems are made of undulator segments and intersection components. LÄS MER

5. 4. Rock Magnetic Studies of Magnetite and Quartzite: Results at Ambient Conditions and From Diamond Anvil Pressure Experiments (~2 GPa)

   Master-uppsats, Uppsala universitet/Geofysik

   Författare :Dimitra Daniil; [2021]
   Nyckelord :magnetic susceptibility; remanent magnetization; mDAC; AF demagnetization; NRM; IRM; ARM; magnetisk susceptibilitet; magnetisk remanens; mDAC; AF demagnetisering; NRM; IRM; ARM;

   Sammanfattning : Numerous techniques are used to study the magnetic history and properties of rocks, which provides important data on the Earth’s interior. In this study we conducted a series of experiments on two different sample sets, comprising pure magnetite (Set1) and a mixture of magnetite-hemoilmenite-bearing quartzite (Set2), in order to gather information about their magnetic susceptibility and remanent magnetization.
