1. Structural analysis of HZO thin film and electrode using X-ray diffraction
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenAbstract : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. READ MORE

2. Reconstructing Past Climate by Grain Size and Magnetic Susceptibility Analysis of Belgium Loess From the Late Quaternary
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Aeolian dust that gets deposited builds up loess sequences that cover 10% of the Earth's continents. Such sequences can be several metres thick with material deposited over thousands of years, and therefore act like archives of past climates. READ MORE

3. The Effect of Alternative Tungsten Carbide Grain Size Distribution on Microstructure and Mechanical Properties in Cemented Carbides
University essay from KTH/MaterialvetenskapAbstract : In the constant pursuit of better-performing cemented carbides, recent studies suggest that a combination of better hardness and toughness can be obtained by changing its WC grain size distribution. As the area is still rather unexplored, this thesis aims to broaden the knowledge and answer whether mechanical properties can be changed by changing the WC grain size distribution, in the context of mining drill bit inserts.

4. Effect of post-treatment of cemented carbide : Microstructural investigation and evaluation of mechanical properties of cemented carbide inserts for rock tool applications
University essay from Karlstads universitet/Avdelningen för maskin- och materialteknikAbstract : Cemented carbides are used in rock tool applications by reason of their beneficial mechanical properties, i.e. a combination of high toughness, wear resistance and hardness. The cemented carbides commonly receive their hardness from tungsten carbides (WC) whereas cobalt (Co) is the dominating binder material. READ MORE

5. The Effect of Cooling Rate on Sintered Cemented Carbides
University essay from KTH/MaterialvetenskapAbstract : Magnetic measurements are useful tools for quality control of cemented carbides. Previous work at Sandvik Mining and Rock Technology has shown that the coercivity increases with increased cooling rate during sintering for a specific grade. READ MORE
