Phase evolution in PLD MgB2 films during the in situ annealing process
The transformation of zero-field-cooled (ZFC) magnetization curves of PLD MgB2 films annealed in situ for different dwell times and at different temperatures is studied within the context of structural analysis. The PLD films were deposited using an off-axis geometry followed by two series of annealing conditions: the dwell time series and the annealing temperature series. ZFC magnetization cur...
متن کاملSurface morphological evolution during annealing of epitaxial Cu„001... layers
Single crystal Cu 001 layers were grown on MgO 001 by ultrahigh vacuum magnetron sputtering at Ts=100 °C. Quantitative surface morphological analyses by in situ scanning tunneling microscopy show that the surfaces exhibit self-affine mound structures with a scaling exponent of 0.82 0.03 and a mound radius rc that increases from 31 8 to 39 6 nm for increasing layer thickness t=24–120 nm. In situ...
متن کاملEvolution of strength and coercivity during annealing of FeCo based alloys
Iron-cobalt alloys are used as soft-magnetic materials in circumstances where a high magnetic saturation is important. There is confusion in the literature about the cause of an observed discontinuity in the variation of strength and coercivity as a function of the temperature at which cold-rolled Fe-Co alloys are annealed. It is shown here using calculations based on published data, that the v...
متن کاملHIGH TEMPERATURE ELASTIC STRAIN EVOLUTION IN Si3N4-BASED CERAMICS
Tension experiments in vacuum were performed on a monolithic Si3N4 sample at 1375°C and a 20Vol% SiCp-Si3N4 composite sample at 1400°C using the new SMARTS diffractometer at the Los Alamos Neutron Science Center. The deep penetration of neutrons facilitated these in-situ studies. In particular, the hkl-dependent strains were measured and the results interpreted by Eshelby-based modeling for the...
متن کاملPhase-Destabilization Mechanism of Polymer-Modified Bitumens in Quiescent Annealing
Bitumen as a binder in coating and insulating materials is modified with polymers to improve its performance in service conditions. Almost all polymers are incompatible with bitumen, and at high temperatures due to relatively very low viscosity of the bitumen phase, are separated from it. These lead to a considerable limitation in the use and handling of polymer-modified bitumens. An understand...
