This study investigates the influence of milling parameters and sintering cycle on microstructure properties cemented carbides with an overal WC–11.5wt%Fe–4wt%NbH–0.5wt%C starting powder composition. The raw material powders were milled mixed in a ring mill or planetary ball sintered at 1150, 1200 1250 °C using spark plasma (SPS). carbide density, Vickers hardness fracture toughness evaluated. ...

Abstract The JCNS has been developing and using in-situ polarized neutron spin filters for many applications. system used analysis on MARIA polarization TOPAS were completed about 10 years ago with the in standard operation users employed a long measurement POLI instrument. In meantime we are progressing several new polarizers based these first two but additional innovations. KWS-1 analyzer dev...

in most cases, fiber reinforced self-compacting concrete (frscc) contains only one type of fiber. the use of two or more types of fibers in a suitable combination may potentially not only improve the overal properties of self-compacting concrete, but may also result in performance synergie. the combining of fibers, often called hybridization, is investigated in this paper for a cimentetious mat...
