2. 1. On the Nature of Cemented Carbide Wear in Rock Drilling

   Author : Ulrik Beste; Staffan Jacobson; Mikael Olsson; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; cemented carbide; wear; rock drilling; rock; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Abstract : WC/Co cemented carbide is a composite material for highly demanding wear applications. The unique combination of hardness (from the WC-phase) and toughness (from the binder Co) gives a material especially suitable for rock drilling. READ MORE

4. 2. Nitride Thin Films for Thermoelectric Applications : Synthesis, Characterization and Theoretical Predictions

   Author : Mohammad Amin Gharavi; Per Eklund; Rickard Armiento; Björn Alling; Camille Pallier; Caterina Zanella; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Thermoelectrics is the reversible process which transforms a temperature gradient across a material into an external voltage through a phenomenon known as the Seebeck effect. This has resulted in niche applications such as solid-state cooling for electronic and optoelectronic devices which exclude the need for a coolant or any moving parts and long-lasting, maintenance-free radioisotope thermoelectric generators used for deep-space exploration.

5. 3. Phase field modeling of precipitation reactions in miscibility gap systems

   Author : Deepjyoti Mukherjee; Joakim Odqvist; Henrik Larsson; Benoît Appolaire; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Precipitation; Discontinuous; Diffusion; Boundary; Phase-field; Miscibility-gap; Cemented carbides; Binary alloys; Materials Science and Engineering; Teknisk materialvetenskap;

   Abstract : As a backbone to the cutting tools and rock drilling industry, cemented carbides have been used widely due to their high hardness and wear resistance. Most commercially used cemented carbides contain a hard phase made of Tungsten carbide (WC) and a binder phase which is generally ductile. READ MORE

6. 4. Leaching results in the assessement of slag and rock materials as construction material

   Author : Mia Tossavainen; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

   Abstract : Extraction of rock material and ore for construction and metal production involves large quantities of wastes and by-products. Iron- and steelmaking slag has durability qualities and latent cementitious properties which are positive in construction. READ MORE

7. 5. Technological properties of rock aggregates

   Author : Eva Johansson; Richard Prikryl; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

   Abstract : The commission of technical geology is to apply geological knowledge to the field of constructional engineering, mining technology, environmental protection, architecture etc. The sector of infrastructure is highly dependent on the production of crushed rock materials as the main constituent of e.g. road and railway constructions.
