Books and publications decision, but is misreads the British market. Engineering education in UK universities takes a different approach. Through design exercises and other means, students are encouraged to use rigorous scientific principles to come up with detailed solutions to problems. Although lightweight books, such as this one, might be useful to expand horizons, they cannot do more than that. There are, of course, other ways to expand horizons. As will be evident, I am not enthusiastic about this slim volume. It makes fair enough light snack, but at the asking price I would want a substantial meal. The publishers should be encouraged to research the UK market thoroughly if they are going to aim at it. J.R.

Steels - Metallurgy and Applications D.T. Llewellyn Butterworth-Heinemann, O.v/brd, 1992, 302 pp, ISBN 07506 1090 5, £45 This is a highly topical book that will benefit metallurgy students as well as engineers and metallurgists concerned with steels. The author has had over 30 years of involvement with the steel industry. Not surprisingly, his insight and experience become apparent as the book unfolds into an easily readable and a valuable source of highly relevant and contemporary information. A good balance exists between theory and practice, i.e. the metallurgy and applications. An important message to the reader is that steel is user-friendly and that its production is a hi/tech industry. The five main sections deal with the technological trends in the industry, lowcarbon strip steel, low-carbon structural steels, engineering steels and stainless steels. Each section begins with an introduction to the relevant metallurgy and the technological/commercial aspects. Wherever appropriate, the pertinent British Standard specificiatJons, current British Steel practices, prices, sales figures, energy consumption levels, development trends, examples of material failures, etc. are included. Generous references to published work and an adequate subject index are provided. The figures, diagrams and tables are clear and well laid out. Personally, I would have liked to have seen a few micrographs of steels. Recent developments and current trends in iron and steel making and continuous casting feature are described in the short, first section. Strip steels (inclusive of tinplate) are discussed in the

second section on the basis of chemistry, processing, property requirements, nature of protective coatings and areas of current/projected applications. Structural steels, their metallurgy, processing, inclusion shape control, applications in ships, offshore structures, bridges, etc. feature in the next section. The section on engineering steels is the longest (approximately 90 pages), very penetrative and covers, for example, composition, heat treatment and properties of machinable, bearing, high speed rail and forging steels, bar and rod products. The final section is on stainless steels and considers such issues as corrosion resistance, cold workability, high temperature, sub-zero properties as well as applications in boilers, prcssure vessels, automotive exhausts and catalytic convertcrs, etc. Common to all grades of steels is the need for uniformity of microstructure which, m turn, leads to consistency of properties within coils, between coils, within bars, sections, etc. This issue becomes particularly relevant in thick plate or forged sections, this being one of the current reasons why certain offshore components are cast rather than fabricated from plate and assembled. The issue of property consistency has also led to new technologies and large investments. Had these issues been included, the book could have become even more comprehensive; perhaps, these items can be considered in the next edition. In summary, this is a highly significant and valuable compilation that reflects on the current state and future trends in steel technology. It is reasonably priced, although a softback edition will place the price within the reach of students. C. Dasarathy

Computational Methods in Materials Science J. E. Mark, M. E. Glicksmann and S. P. Marsh (Eds) MRS (Vo1278 S)'mposium Proceedings), 1992, 401pp, ISBN, 1-899-173-5, $62.00 Some have argued that modern computational methods in materials science and engineering are literally redefining the bounds of knowledge from which we predict structure property relationships, perhaps changing the historically descriptive character of this science and much of the engineering for ever. This new proceedings volume from the Materials Research Society focuses on new developments in modern computational methods applied to model and predict the responsc of materials under a diverse range of physico-chemical conditions, it documents proceedings t¥om a symposium presented at the 1992 MRS Spring Meeting in San Francisco and covers modelling techniques: polymers;

Tissue-inducing Biomaterials L.G. Cima and E.S. Ron (Eds) MRS (Vo1252 Symposium Proceedings), 1992, 407pp, ISBN 1-55899-146-8, hardcover, $68.00 The philosophy underlying the design of permanent implants is shifting from that of tissue replacemcnt to that of tissue repair. This is adding another dimension to biomaterials-aided tissue repair, extending it to metabolic organs such as the liver and pancreas in addition to the traditional realm of structural tissues like bone. Topics covered in this new book include osteo-inducing materials: preparation and physicochemical characterization, cell and tissue interactions; collagen-based scaffolds: fundamental cellsubstrate interactions and tissue-specific materials: materials for morphogen delivery: biodegradable synthetic polymers and biomimetic materials for tissue reconstruction.

Users' guide to testing non-conductive materials A users" guide to the non-destructive testing (NDT) of non-conducting materials has been published by ERA Technology. The 110-page guide deals with the less well documented current NDT techniques which are applicable to newer materials such as particle- and fibre-filled composites and ceramics: referred to in the guide as non-conducting materials. Six NDT techniques are covered in separate sections of the report: ultrasonic, sonic, radiological, optical, thermography and microwave. Each section sets out the basic principles of the various test methods and their applications and concludes with a quick-reference summary. The information provided can be used also as a basis for deciding the suitability of a particula, technique for additional applications not covered by the report. The use of computers to extend the range of tests and to make the data they yield 'user friendly' is given emphasis. Copies of the ERA report Critical Survey qf Non-Destructive Testing o[ Non-Comhtcting Materials (No. 920109R) are available at a cost of £175 from Publication Sales, ERA Technology Ltd, Cleeve Road, Leatherhead, Surrey KT22 7SA.
