Influência do tamanho médio de grão nas propriedades ferroicas de compósitos magnetoelétricos particulados
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2016-04-08)
In the case of composites materials, which presents the magnetoelectric coupling,
there are so many questions about the influence of the microstructure on the coupled
and uncoupled properties. Thereby, this work proposes ...
The study of ternary carbides formation during SPS consolidation process in the WC-Co-steel system
(ELSEVIER SCI LTD, 2009)
Tungsten carbide has a wide range of applications, mainly cemented carbides made of WC and Co, as wear resistant materials. However, the high cost of WC-Co powders encourages the use of a substrate to manufacture a ...
Microstructural and electrical characterizations of W-doped La2Mo2O9 prepared by spray pyrolisis
(Springer Heidelberg, 2013-12)
La2Mo2 − xWxO9 (x=0, 0.5, 1.0, and 1.3) nanocrystalline powders were synthesized by spray pyrolysis (SP) assisted by an ultrasonic atomizer. Microstructure, sinterability and thermal stability of the prepared powders ...
Size-induced diffuse behavior in Pb0.89La0.11Zr0.40Ti0.60O3 nanocrystalline ferroelectric ceramics
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The Pb1-xLaxZryTi1-yO3 system is a perovskite ABO(3) structured material which presents ferroelectric properties and has been used as capacitors, actuators, transducers and electro-optic devices. In this paper, we describe ...
