ab phase separation in the amorphous zr_4_1ti_1_4cu_1_2 5ni_1_0be_2_2 5 alloy annealed at 620 and 643 k has been investigated by means of the in situ smallangle neutron scattering sans technique the alloy decomposes into two supercooled liquid phases with the volume fraction of about 10 20 for the second phase the interphase boundary causes q 4 scattering behaviour the phase separation rate depends strongly on temperature with a rather sluggish coarsening in the late stage the kinetic exponent of this coarsening stage was found to be about 0.06 to be compared with the lifshitzwagner exponent 0.33 author dei amorphousstate annealing beryllium copperoxides neutrondiffraction nickelalloys phase studies smallanglescattering temperaturedependence temperaturerange04001000k titanium basealloys zirconiumalloys dec alkalineearthmetals alloys chalcogenides coherentscattering coppercompounds diffraction elements heattreatments metals oxides oxygencompounds scattering temperature range titaniumalloys transitionelementalloys transitionelementcompounds is issn 09538984 cc s75 c1 s75 cd condensed matter physics superconductivity and superfluidity ud 4317 an 43033510 record 19 of 628 inis 2011/012012/05 ti dielectric properties of bati ceo_3 from 10 2 to 10 5 hz in the temperature range 85700 k au zhiyu chenang zhijing vilarinho,p.m baptista,j.l department of ceramic and glass engineering university of aveiro 3810 aveiro portugal so journal of physics condensed matter 7 apr 1997 v 914 p 30813088 country of input malaysia this record replaces 32021428 nt available online at the web site for the journal of physics condensed matter issn 1361648x http www.iop.org py 1997 la english ci unitedkingdom pt journalarticle ab bati_1 xce_xo_3 ceramics with x 0.1 0.2 0.3 0.33 0.4 and 0.5 have been synthesized by the mixed oxide method dielectric measurements were performed for bati_1 xce_xo_3 ceramics from 10 2 to 10 5 hz in the temperature range 85 700 k the dielectric measurements confirmed that the solid solution range extends up to about x=0.3 in the solid solutions the temperature of the permittivity maximum was shifted at a rate of 7 k/mol ce atom and the permittivity maximum decreased with increasing ce content the temperature and frequency dependence of the permittivity was fitted by the curie weiss law beyond the transition temperature and characterized by parameters that are used to describe relaxor behaviour author dei barium ceramics cerium curieweisslaw dielectricproperties frequencydependence oxides permittivity temperaturedependence temperaturerange00650273k temperaturerange0273 0400k temperaturerange04001000k titanium transitiontemperature dec alkalineearthmetals chalcogenides dielectricproperties electricalproperties elements metals oxygencompounds physicalproperties rareearths temperaturerange thermodynamic properties transitionelements
