Steels,other materials. Toughness can be considered straightforwardly as sensitivity or resistance to fracture. Generally, toughness will be degraded when strength is increased, that is, there is a trade-off between toughness and strength of materials.

Ductile Cast Iron,generally assumed as brittle compared to steels, there are only few applications to structural elements where fracture toughness becomes major concern. In addition, various new materials are appearing in recent years and therefore less interest is attracted by cast iron, which is generally believed to be an old material.

Metal Matrix Composites,owever, they are not immune to the damage engendered in brittleness and low fracture toughness, as shown by many other advanced materials. Therefore, problems of reliability such as fatigue characteristic and improvement of fracture toughness by controlling fracture characteristics are important subjects for promoting practical application of MMC.
