Passive Energy Devices in Ceramics

Buildings with scales, buildings that sweat: this paper proposes two strategies for a materially grounded, performance-based architecture which leverages the strengths of computation and CNC fabrication against the basic properties of traditional ceramics.

Kinetic model for self-crack-healing in ceramics and possibility of turbine blade applications

Self-crack-healing behaviors in alumina/ silicon carbide (SiC) nanocomposites (agent diameter of 270 nm) having the semi-eliptical surface crack were investigated at various healing temperatures TH and oxygen partial pressures pO2 in standard pressure. The results showed the complete strength recovery was attained by heating at test temperature...

Increase in critical stress for crack-healing of Si3N4/SiC ceramics by shot peening

The effects of shot peening on the critical stress for crack-healing of Si3N4/SiC composite ceramics were investigated. Shot peening was carried out on a Si3N4/SiC composite with a surface crack by using yttrium-stabilized zirconia beads. Shotpeened specimens were crack-healed at 1100 °C for 5 h under a tensile stress (?app) in the range 0–500...
