Abstract Scope |
Self-healing aluminium alloys are new generation of light metals with high strength, good corrosion resistant and well transformability. Adding a new property, possibility of self-healing process, to this excellent materials, the outstanding light metals are being developed.
Aluminium alloys are employed extensively for aircraft and automobile applications. In both cases the application is limited by slow fatigue damage evolution during service. If crack growth could be postponed the life span of components would be increased and the frequency of inspections reduced. An intriguing concept to achieve this is the incorporation of self-healing mechanisms into engineering materials. Self-healing of damage is an important concept in biological materials but is, so far, not common in engineering materials. Aluminium alloys, particularly, have been considered because they show, even at room temperature. In our study, aluminium alloy of series AA 7xxx is being developed. |
