4. 2. Microstructure of Cermets

   Author : Per Lindahl; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; thermodynamic; microchemistry; N ; AP-FIM; Ti C; cutting tools; SEM; cemented carbide; TEM; sintering;

   Abstract : The microstructure of several TiC-TiN-Mo2C-WC-Co/Ni model alloys and a commercial (Ti,Ta,W,Mo)(C,N)-(Co,Ni) type cermet was studied using x-ray diffraction, optical microscopy, scanning electron microscopy, analytical electron microscopy and atom probe field ion microscopy. In addition thermodynamical calculations were made in order to understand the development of the microstructure during sintering. READ MORE

5. 3. Dynamic Modeling of Hydropower Generators

   Author : David Rondon; Jan-Olov Aidanpää; Rolf Gustavsson; Florian Thiery; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinkonstruktion; Machine Design;

   Abstract : Modeling the dynamics of hydropower generators has been the aim pursued by many studies, as providing a reliable model would lead to more cost-effective designs. Hydropower generators comprise many parts, tilting-pad bearings, shaft, rotor rim, and stator among them, that contribute to the system's nonlinearities. READ MORE
