Preface to Second Edition My concept for this book,namely to show the connection be- tween the technical and the cultural,economic,ecological,and societal aspects of materials science seems to have been realized judging from the enthusiastic reception of readers coming not only from the hard sciences,but also from the humanities and medicine.Indeed,the first printing sold out less than two years after publication,which made reprinting necessary and gave me the opportunity to make some changes and additions.The com- ments of many students who took a course based on this book and by colleagues from all over the world confirmed my hunch that many individuals would be interested not only in the phys- ical and technological aspects of materials but also in how ma- terials and the goods which were made of them shaped the de- velopment of mankind.By relating history and technology in this text many students were disabused of the idea that "most every- thing was invented in the past hundred years"(and in the USA). When contemplating a second edition,I withstood the temp- tation to substantially expand the book by including major new topics and a more detailed treatment of several subjects.If sub- stantial in-depth treatment of a given topic is wanted,reference should be made to one of the many encyclopedic materials sci- ence books that have two or three times more pages.One should realize,however,that the contents of these larger books cannot be covered in a customary three-credit semester course.This ne- cessitates that each teacher select those topics which he/she deems to be most important,that is,with which he/she is most familiar.I have chosen to restrict the presented material and the depth of its treatment to that which is realistically digestible in an introductory course in materials science without overbur- dening the students with too much detail.Clearly,this text is not meant to be encyclopedic,but instead aims to whet the appetite of its readers and to inspire them to further explore the proper-

It is a challenging endeavor to trace the properties and the development of materials in the light of the history of civilization. Materials such as metals, alloys, ceramics, glass, fibers, and so on have been used by mankind for millennia. Actually, materials have shaped entire civilizations. They have been considered of such importance that historians and other scholars have named certain ancient periods after the material which was predominantly utilized at that respective time. Examples are the Stone Age, the Bronze Age, and the Iron Age. As time progressed the materials became increasingly sophisticated. Their properties were successively altered by man to suit ever-changing needs. We cannot but regard with utmost respect the accomplishments of men and women who lived millennia ago and who were capable of smelting, shaping, and improving the properties of materials. Typical courses on world history expose students mainly to the description of major wars, the time span important rulers have reigned, and to the formation, expansion and downfall of world empires. Very little is generally said about the people who lived and toiled in ancient times and about the evolution of civilizations. This book traces the utilization, properties, and production techniques of materials from the Stone Age via the Bronze Age and the Iron Age up to modern times. It explains the physical properties of common materials as well as those of “exotic materials” such as superalloys, high-tech ceramics, optical materials, electronic materials, and plastics. Likewise, natural and artificial fibers and the technique of porcelain- and glass-making are covered. Moreover, this book provides a thorough introduction into the science and engineering of materials, covering all essential features that one would expect to find in a horizontally integrated introductory text for materials science. Specifically, the book presents the mechanical, electrical, magnetic, optical, Preface to the First Edition

xii Preface to the First Edition and thermal properties of all materials including textiles,fibers, paper,cement,and wood in a balanced and easily understand- able way.This book is not an encyclopedia of materials science. Indeed,it is limited in its depth so that the content can be con- veniently taught in a one-semester (15-week),three-credit-hour course.Nevertheless,the topics are considered to be essential for introducing engineers and other interested readers to the fasci- nating field of materials science. Plenty of applied problems are given at the end of the techni- cal chapters.The solutions for them are listed in the Appendix. The presentation follows an unusual sequence,starting with a description of the properties of the first materials utilized by man, such as stone,fiber,and copper.Subsequently,the differences between these materials are explained by considering their atom- istic structure,the binding forces between the atoms,and their crystallography.A description of the Bronze Age is followed by the treatment of alloys and various strengthening mechanisms which are achieved when multiple constituents are blended to compounds.The properties of iron and steel are explained only after an extensive history of iron and steel making has been pre- sented.In Part II,the electronic properties of materials are cov- ered from a historical,as well as from a scientific,point of view. Eventually,in Part III the historic development and the proper- ties of ceramics,glass,fibers and plastics as we understand them today are presented.The book concludes with a chapter on eco- nomics,world resources,recycling practices,and ecology of ma- terials utilization.Finally,an outlook speculating on what mate- rials might be utilized 50 years from now is given.Color reproductions of relevant art work and artifacts are included in an insert to show the reader how materials science is interwo- ven with the development of civilization. This book is mainly written for engineering,physics,and ma- terials science students who seek an easily understandable and enjoyable introduction to the properties of materials and the laws of physics and chemistry which govern them.These students(and their professors)will find the mixture of history,societal issues, and science quite appealing for a better understanding of the con- text in which materials were developed.I hope,however,that this book also finds its way into the hands of the general read- ership which is interested in the history of mankind and civi- lization as it relates to the use and development of materials.I trust that these readers will not stop at the end of the historical chapters,but instead will continue in their reading.They will dis- cover that the technical sections are equally fascinating since they provide an understanding of the present-day appliances and tech-

These students (and their professors) will find the mixture of history, societal issues, and science quite appealing for a better understanding of the context in which materials were developed. I hope, however, that this book also finds its way into the hands of the general readership which is interested in the history of mankind and civilization as it relates to the use and development of materials. I trust that these readers will not stop at the end of the historical chapters, but instead will continue in their reading. They will discover that the technical sections are equally fascinating since they provide an understanding of the present-day appliances and techxii Preface to the First Edition
