Direction Of Polarization

To induce fine engineered domain configurations into potassium niobate (KNbO3) single crystals, two kinds of methods were performed, i.e., (1) high DC electric field exposure along the opposite direction of polarization of KNbO3 single-domain crystals at room temperature, and (2) introduction of randomly oriented fine domain configuration by heat treatment at 700 °C and then high DC electric field exposure along [001]c direction of KNbO3 multidomain crystals at room temperature. When the method (1) was performed, finally, the poled KNbO3 crystals became to single-domain state again through the formation of multidomain state. On the other hand, the KNbO3 multidomain crystals were obtained by using the method (2), and an enhancement of piezoelectric-related properties was observed.

Nanoindentation measurements in single crystals of carbamazepine form III show that the (020) face is stiffer and harder than the (002) and (101) faces. AFM imaging and molecular simulations reveal that the (020) plane is the most likely slip plane.

With single crystals of copper, measurements have been made on the variation of the amount of easy glide with the orientation of the crystal axes relative to the direction of tension. At —180° C it has been shown that this variation can be quantitatively expressed by a specific hardening on the active glide planes, which does not exist for the latent glide planes, and a general hardening which applies to both active and latent glide planes. This is compared with the behaviour of hexagonal metals. The occurrence of double glide is analyzed. The variation of glide properties with temperature has been measured for one particular orientation, and the coefficient of specific hardening shown to be roughly independent of temperature. The critical shear stress is also very little affected by temperature, but depends somewhat on orientation. The glide behaviour at high temperature has been found to be influenced largely by the occurrence of deformation bands. A few measurements have been made on gold.
