12. Conclusion
 Over the period MMC’s proved their importance and are
contributing the progress and evolution of mankind.
 The MMCs have satisfied the designer conceptions, in such a
way that act as functional materials for advanced
applications. These composites can solve the major problems
associated with many applications only if these are designed
to achieve the standards.
 The high cost of MMCs is attributed to the cost of reinforced
materials and matrix metals and the processing expenses. At
present, several vapor deposition processes are being
employed in the fraction of MMCs, but still the cost factor is
keeping them away from day-to-day applications. Novel, cost-
effective methods have to be accomplished in order to achieve
the market for MMCs.
