Preface

In recent years, the concept of advanced structural materials has changed from advanced composites

and intermetallics to microelectromechanical systems (MEMS), cellular materials, biomaterials,

shape memory alloys, amorphous alloys, and nanostructured materials. Many of the intermetallic and

composite systems that appeared promising just a decade ago are no longer considered by many to be

serious candidates for near-term applications in the next decade. Within this context, a number of

existing structural materials, such as titanium and cobalt alloys, have also embraced advanced

applications in ways that enhance their status as advanced structural alloys/systems.

This book is written for both the non-specialist and the specialist. It is written for those who want

to develop an understanding of the breadth and depth of current advanced structural materials.

Although each chapter has been written by an expert in the ﬁeld, no prior knowledge of a given

material system is assumed. Each chapter, therefore, presents the fundamental concepts (structure

and properties of materials) and the applications of advanced structural materials.

Due to the huge nature of the ﬁeld, we have been forced to deﬁne advanced structural materials

as cutting-edge systems that are currently in structural use, or future systems that appear to have the

promise for near-term structural applications. Hence, we do not include chapters on advanced

intermetallics and ceramics, which remain as long-term contenders for future large-scale structural

applications. Nevertheless, we hope that the rich array of selected topics will provide readers with

useful insights into the structure, properties, and applications of some of the systems that are

currently considered advanced structural materials.

The book is divided into four sections. In section I, a broad introduction to advanced structural

materials is presented. This is followed by section II, in which materials at the frontiers of emerging

applications are presented. These include some aspects of biomaterials, MEMS, amorphous

materials, and nanotechnology. In section III, existing advanced structural alloys are described

before focusing on high temperature structural materials in section IV.

We are grateful to authors for taking time out of their busy schedules to prepare their chapters.

We are also grateful to Ms. Betty Adam of Princeton University for her tireless efforts in

coordinating the correspondence with the authors, and synthesizing their inputs into a coherent

document. It is hard to imagine how this book could have been completed without her skilled help.

This book was initiated by Dawn Wechsler and Janet Sachs of Marcel Dekker. Since their initial

efforts, we have been guided by Shelley Kronzek of Taylor & Francis Books, CRC Press. We would

like to thank her for her vision and her patience. We hope that this book will be useful to senior

undergraduate and graduate students, practicing materials scientists and engineers, researchers, and

those who simply want to learn more about advanced structural materials.

Much of my current understanding of advanced structural materials has been nurtured by

program managers who have supported my research over the past two decades. I would, therefore,

like to thank Charles Whitesett (McDonnell Douglas), Dick Lederich (McDonnell Douglas),

Shankar Sastry (McDonnell Douglas/Washington University), Oscar Dillon (NSF), Dan Davis

(NSF), Jorn-Larsen Basse (NSF), George Yoder (ONR), Julie Christodolou (ONR), Chuck Ward

(AFOSR), Bruce MacDonald (NSF), Majia Kukla (NSF), Ulrich Strom (NSF), Tom Rieker (NSF),

Joe Akkara (NSF), Tom Weber, Lance Haworth, Adriaan Graaf, and Carmen Huber (NSF) for their

support of my efforts. I would also like to thank NSF (DMR Grant No. 0231418) for providing the

ﬁnancial support used to coordinate the preparation of this book.

Finally, I would like to thank my dear wife, Morenike, and my children, Rotimi, Deji, and Wol´

for allowing me the time to work on yet another book project. I hope that the time spent on this

project will help to enrich the lives of others, just as it has enriched mine.
