Ceramics

Ceramics, when analyzed under microscopy, exhibit a microstructure characterized by densely packed, crystalline or amorphous particles with distinct grain boundaries and often reveal unique phase compositions.

Numerical and Experimental Investigation on the Self-Healing Potential of Interpenetrating Metal–Ceramic Composites

This study investigates the potential and feasibility of self-healing in an interpenetrating metal ceramic composite (IMCC). The cracks in the damaged composite are filled and closed by a liquid metal alloy when heated, reducing stress concentrations and improving mechanical properties compared to the predamaged composite. Numerical models are used to analyze stress concentrations and the restoration of mechanical properties, while experimental testing demonstrates the potential for self-healing in the IMCC. Although the experimental self-healing is currently only moderately feasible, the study highlights the potential for extending the service life of IMCC engineering components through further development of the self-healing approach.
