1. The Application of Multivariate Statistical Process Control during Industrial Hot Isostatic Pressing Sintering Processes : A Case study at Seco Tools AB
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälleSammanfattning : This Master's thesis focuses on improving the understanding and monitoring of the Hot Isostatic Pressing (HIP) sintering process used by Seco Tools AB to manufacture cemented carbides for cutting tools. While essential for producing cutting tools with superior hardness and toughness the HIP sintering process introduces a complex relationship between the selected process parameters and the achieved materials properties.

2. 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/MaterialvetenskapSammanfattning : 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. Paleomagnetic and Thermomagnetic Studies on Rock Samples from COSC - 1 Drilling Project
Master-uppsats, Uppsala universitet/GeofysikSammanfattning : 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. The Effect of Alternative Tungsten Carbide Grain Size Distribution on Microstructure and Mechanical Properties in Cemented Carbides
Master-uppsats, KTH/MaterialvetenskapSammanfattning : 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.

5. The Effect Of Sub Tx Heat Treatments On The Magnetic Properties Of An Fe-based Bulk Metallic Glass
Kandidat-uppsats, Uppsala universitet/MaterialfysikSammanfattning : Metallic glasses produced with Selective Laser Melting (SLM) often contain internal mechanic stress. This internal stress can have an impact on the magnetic properties of the material due to its connection to the magnetic anisotropy of the material. LÄS MER
