High Performance Relaxor-Based Ferroelectric Single Crystals for Ultrasonic Transducer Applications
Relaxor-based ferroelectric single crystals Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT) have drawn much attention in the ferroelectric field because of their excellent piezoelectric properties and high electromechanical coupling coefficients (d33~2000 pC/N, kt~60%) near the morphotropic phase boundary (MPB). Ternary Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3 (PIN-PMN-PT) single crystals also possess outstan...
متن کاملSingle Crystal Turbine Blade Inspection Using a 2d Ultrasonic Array
In this paper a non-destructive method for inspecting jet-engine turbine blades for root cracking is developed. This method utilises 2D ultrasonic arrays to enable the detection and characterisation of sub-surface cracks in three-dimensions. The majority of modern turbine blades are manufactured from single crystals of nickel based superalloys which exhibit high elastic anisotropy. This complic...
متن کاملElastic, dielectric and piezoelectric characterization of single domain PIN-PMN-PT: Mn crystals.
Mn modified 0.26Pb(In(1/2)Nb(1/2))O(3)-0.42Pb(Mg(1/3)Nb(2/3))O(3)-0.32PbTiO(3) (PIN-PMN-PT:Mn) single crystals with orthorhombic perovskite crystal structure were polarized along [011] direction, resulting in the single domain state "1O." The complete set of material constants was determined using the combined resonance and ultrasonic methods. The thickness shear piezoelectric coefficient d(15)...
متن کاملThe strength of PIN–PMN–PT single crystals under bending with a longitudinal electric field
The effect of an electric field on the bending behavior of [001] oriented and poled relaxor Pb(In1/2Nb1/2)O3–Pb(Mg1/3Nb2/3)O3–PbTiO3 (PIN–PMN–PT) single crystals was measured using a four point bending apparatus with a longitudinal electric field applied to the bar during bending. The surface finish and electric field amplitude were observed to affect the bending strength. Polished surfaces imp...
