Re-Austenitisation of Thin Ferrite Films in C–Mn Steels during Thermal Rebound at Continuously Cast Slab Corner Surfaces

Physical Modeling of Steel Delivery during Thin Slab Continuous Casting

A full scale physical model of a thin slab caster with a four-hole design submerged entry nozzle (SEN) was constructed. On the basis of the dimensionless Reynolds and Froude similitude criteria, the fluid flow in a full-scale model is similar to that of the actual system and, hence, the data obtained from the water model can be applied to the actual system. In order to determine the optimum ope...

Thermal conductance of Nb thin films at sub-kelvin temperatures

We determine the thermal conductance of thin niobium (Nb) wires on a silica substrate in the temperature range of 0.1-0.6 K using electron thermometry based on normal metal-insulator-superconductor tunnel junctions. We find that at 0.6 K, the thermal conductance of Nb is two orders of magnitude lower than that of Al in the superconducting state, and two orders of magnitude below the Wiedemann-F...

PULSED LASER DEPOSITION OF Ni-Zn FERRITE THIN FILMS

Thin Ni0.5 Zn0.5 Fe2 O4 ferrite films were grown on different condition on different substrates using pulsed laser deposition technique. Studying the influence of the energy of the laser beam, of the O2 pressure, of the substrate temperature, and of the distance between the target and the substrate on the microstructure and on the magnetic properties were established optimal conditions for PLD ...
