6. Microstructure and Mechanical Properties of Plasma Atomized Refractory Alloys
Abstract : Plasma centrifugal atomization is a method widely used in the production of spherical powders of metals and alloys with relatively low melting points. A novel plasma centrifugal atomization process suitable for high melting point materials (i.e. 3500 ᵒC and above) was developed by Metasphere Technology AB, currently Höganäs Sweden AB. READ MORE

7. Atomic scale modeling of ordering phenomena
Abstract : Ordering phenomena in materials often have a crucial impact on materials properties. They are governed by the competition between entropy and energy. Accordingly simulating these aspects requires the construction of models that enable a computationally efficient exploration of the relevant configuration space. READ MORE

8. High power bipolar junction transistors in silicon carbide
Abstract : As a power device material, SiC has gained remarkable attention to its high thermal conductivity and high breakdown electric field. SiC bipolar junction transistors (BJTs) are interesting for applications as power switch for 600 V-1200 V applications. READ MORE

9. Environmental, Resource and Health Assessments of Hard Materials and Material Substitution: The Cases of Cemented Carbide and Polycrystalline Diamond
Abstract : The conventional hard material used in manufacturing industry, cemented carbide (WC-Co), mainly consists of the geochemically scarce elements tungsten and cobalt. This use of scarce resources could potentially be avoided by a material substitution to the more abundant and largely carbon-based material polycrystalline diamond (PCD). READ MORE

10. Insights into wear and deformation of alternative binder hardmetals
Abstract : This work presents new insights into how hardmetals with alternative binders as well as cobalt based references react to wear and deformation. The main focus has been on hardmetals for steel turning, but also on studying certain fundamental properties of the new binder materials. READ MORE
