Crack healing behaviour of a Cr2AlC ceramic (abstract)

A conceptual study into the potential of MAX-phase ceramics for self-healing of crack damage

The reduction of maintenance and replacement work costs is an important driving force in the development of high temperature materials (T>800 °C) that can autonomously heal damage as a result of local cracks. In recent years some potential routes involving the addition of sacrificial particles have been identified, yet these systems have the...

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...
