Influence of sample thickness on the performance of photostrictive ceramics
(Amer Inst Physics, 1998)
Ferroelectric materials with high photovoltaic properties are of interest for new optical devices such as photostrictive ceramic actuators. However, fabrication of these devices requires development of materials exhibiting ...
An ultrasonic motor using a metal-ceramic composite actuator generating torsional displacement
(Japan J Applied Physics, 1998)
An ultrasonic motor composed of three components; a stator, a rotor and a ball bearing is proposed. The stator is made of an active piezoelectric ring, poled in the thickness direction and bonded with two windmill-like ...
Cyclic crack growth behaviour of two nickel base turbine disc alloys
(Kluwer Academic Publ, 1998)
The high temperature fatigue crack growth behaviour of the nickel base superalloys Alloy 718 and Rene 95 (specimen thickness = 4.1 mm) were investigated and compared with each other. Fatigue crack propagation (FCP) tests ...
