Abstract

Piezoelectric thick high dielectric constant lead-zirconate-titanate (PZT)/PZT composite films are directly coated onto Al plates by using sol-gel spray technique. The results have shown that, for 2 mm thick aluminum plates, shear horizontal plate acoustic waves (PAW) are the best for the line defect detection, which have agreed well with those obtained by a finite-difference-based method.

Abstract

Several theoretical analyses are conducted to explain the design and working of the high-Q, quartz thin film resonators that work at a frequency of 3.4GHz. The resonators are shown to exhibit excellent frequency-temperature behavior and hence are widely used in various different high-frequency timing devices.

Abstract

A low-matrix-ratio [Nb.sub.3]Al wire is fabricated and the effects of the rapid heating/quenching (RHQ) current and the area reduction (AR) after the RHQ process are studied. The studies have shown that the optimum RHQ current to obtain high [J.sub.c] is the current at the higher edge of the plateau region and the AR process has affected the transformation process that has determined the quality of the A-15 phase.
