Abstract

A procedure for registering damage to a material including a metallic matrix and ceramic particles embedded in it. A volume-increasing phase change of the particles is suppressed by the pressure exerted on them by the metallic matrix. However, if a crack appears in the material, there is a phase change of the particles to a volume-increased phase which is detected by determining a measurement representing the proportion of the volume-increased phase.
