Abstract
Recently, there has been a huge interest in materials that can self-heal, as this property can potentially increase materials lifetime, reduce replacement costs, and improve product safety and reliability. Self-healing systems can be made from a variety of polymers, ceramics and metallic materials. Its applicability in metallic systems is a longing which is felt could revolutionize material design considering the use of these grades of material in stress- and load-bearing applications. This paper highlights, from a materials science perspective, the philosophical foundations propelling research in self-healing materials. It reviews the methods currently deplored for developing self-healing metallic materials and current areas of practical applications. It surmises with a critical look at challenges posed by this method of materials design and applicability in service and contemplates a future which may not be assured but will be eternally captivating and filled with compromises.
