Metal matrix composites, as the name suggests, consist of fibres or particles surrounded by a matrix of use of a metal matrix offers the potential of producing a composite with very high stiffness and strength as well as very high temperature resistance. The temperature resistance is not only superior to polymer matrix composites but also to the pure metal itself.   The authors were motivated to prepare this book by the absence of any recent comprehensive book on titanium. The intent of this book is to provide a modern compendium that addresses both the phyical metallurgy as well as the applications of titanium. Until now the only book on this subject is that by Zwicker which was written in German and published almost 30 years ago.
