Fatigue Behavior of Cracked Piezoelectric Ceramics in Cyclic Three-Point Bending under AC Electric Fields

Development, Characterization, and Piezoelectric Fatigue Behavior of Lead- Free Perovskite Piezoelectric Ceramics

The development of lead-free perovskite piezoelectrics as environmentally compatible alternatives to lead zirconate titanate (PZT) has received significant attention recently. Two main categories of lead free perovskite piezoelectric ceramic systems were investigated as potential replacements to lead zirconate titantate (PZT) for actuator devices. First, solid solutions based on Li, Ta, and Sb ...

Corrosion Fatigue Studies on a Bulk Glassy Zr-Based Alloy under Three-Point Bending

Corrosion fatigue (CF) tests were carried out on bulk glassy Zr52.5Cu17.9Al10Ni14.6Ti5 (Vitreloy 105) samples under load-controlled three-point bending conditions with a load ratio of R = 0.1 in 0.01 M Na2SO4 + 0.01 M NaCl electrolyte. During cyclic testing, the bar-shaped specimens were polarized in situ at constant potentials and the current was monitored. Three different anodic potentials wi...
