Strength Reliability Evaluation of Ceramics with Machining Damage.

Both High Reliability and Giant Electrocaloric Strength in BaTiO3 Ceramics

BaTiO₃ has a giant electrocaloric strength, |ΔT|/|ΔE|, because of a large latent heat and a sharp phase transition. The electrocaloric strength of a new single crystal, as giant as 0.48 K·cm/kV, is twice larger than the previous best result, but it remarkably decreased to 0.18 K·cm/kV after several times of thermal cycles accompanied by alternating electric fields, because the field-induced pha...

Abrasive machining of advanced technical ceramics

The high cost of ceramic components can be associated with complex and time-consuming postmachining, which is currently done by using abrasive machining processes. The IWF and Fraunhofer-IPK are undertaking research activities in the field of abrasive machining which aim at developing and optimizing technologies to expand the application field and to increase productivity of high-performance ma...

Strength evaluation of sintered ceramics by dynamic crack path model

Bond strength evaluation of the veneering-core ceramics bonds.

OBJECTIVE The purpose of this study was to determine whether the bond of veneering porcelain to a ceramic core in bilayered ceramics was similar to that of the metal ceramic control of well known behaviour. STUDY DESIGN Six groups of nine specimens each were fabricated, whose dimensions were 15 mm long and 8 mm in diameter at the core, and 2 mm long and 8 mm in diameter for the veneer. The gr...
