Piezoelectric composite film for acoustic emission detection
(2009-12-01)
The continuous technological advances require materials with properties that conventional material cannot display. Material property combinations are being the focus to the development of composite materials, which are ...
Physical properties of self-polarized PZT thin films at compositions around the morphotropic phase boundary
(Trans Tech Publications Ltd, 2014-01-01)
The physical properties of self-polarized PbZr1-xTixO3 thin films with no preferential orientation in a range of compositions 0.46 <= x <= 0.50 were investigated. Structural analysis revealed the coexistence of ...
Size-dependent phase transitions in nanostructured zirconia-scandia solid solutions.
(Laboratório Nacional de Luz Síncrotron.Campinas, 2013-02-26)
Size effects on phase stability and phase transitions in technologically relevant materials have received growing attention. Several works reported that metastable phases can be retained at room temperature in nanomaterials, ...
Ultrasonic material characterization using diffraction-free PVDF receivers
(2010-01-01)
This work describes the use of a large aperture PVDF receiver in the measurement of density of liquids and elastic constants of composite materials. The density measurement of several liquids is obtained with the accuracy ...
Preparation Of Fine Powdered Composite For Latent Heat Storage
(Amer Inst PhysicsMelville, 2016)
Manufacture of continuous metal matrix composite strip reinforced by particulate materials from the semisolid processing
(2019-01-01)
Strip casting is a new method of producing metal matrix composites. Two-roll melt dragged processing (TRMD-ing) and single-roll melt dragged processing (SRMD-ing) methods were used to study the manufacture of 2-mm-thick ...
Stacking faults in SiCf/SiC composite obtained by chemical vapor reaction process
(2008-12-01)
SiC fiber-reinforced SiC matrix composite (SiCf/SiC) is one of the leading candidates in ceramic materials for engineering applications due to its unique combination of properties such as high thermal conductivity, high ...
Polypropylene composites manufactured from recycled carbon fibers from aeronautic materials waste
(2017-01-01)
Carbon fiber composites are used in several industries such as, aerospace, automotive, civil engineering, sports goods and technical applications due to its low-weight, strength and stiffness. However, the technology of ...
Microstructure, crystalline phase, and dielectric property analyses of TiO2 composition with ZrO2 addition
(2010-12-15)
For microwave applications, including mobile and satellite communications, ceramic resonators should have a high dielectric constant, low dielectric losses, and high frequency stability. In this sense, TiO2-ZrO 2 ceramics ...
Structure and properties of donor doped barium titanate prepared by citrate process
(2002-01-01)
Niobium doped barium titanate was prepared using two procedures. First, doped barium titanate was prepared starting from citrate solutions of all components and second, pure barium titanate powder was obtained from the ...
