385 Forces, and Bending Moments; Stresses and Deflections in Beams; Beam Design; Combined Stresses; and Columns. The reviewer considers this a valuable introductory text book which should be very useful to students of training establishments and technical colleges in different branches of engineering. The writing is clear and straightforward, and it is good value for money.

D e v e l o p m e n t s in Pressure Vessel T e c h n o l o g y -- 4, Edited by R.W. Nichols,

Applied Science Publishers, London, 1983, ISBN 0-85334-223-7, viii + 313 pages, illustrated, hard-cover, £40. This book is the fourth in a series covering topics of interest to pressure vessel technology. The previous volumes have covered Flaw Analysis, Inspection and Testing, and Materials and Fabrication. This volume is concerned with pressure vessel design for specific application other than nuclear reactors, rockets and aerospace, and while relating to specialised extensions from the conventional pressure vessel engineering of the British Standards and the ASME Boiler and PressureVessel Codes, still involves considerations of general interest. Examples of these topics representing aspects which, to some extent, have to be considered in m a n y non-specialised applications, are the effects of very high pressure, high-temperature, corrosive environments, external pressure and vacuum conditions and the additional hazards of transportation. The first chapter is concerned with the design procedures to be adopted when vessels are subjected to high temperatures and covers topics such as extensive plasticity, creep, fatigue, creep-fatigue and intergranular embrittlement which must be recognised for safe design. The ASME design approach is followed although other methods are discussed. Crossland has an excellent chapter on vessels subjected to very high internal pressures, summarising extensive design information peculiar to such vessels. A different approach to indicating the problems that may occur in assessing corrosion of reaction vessels is provided in Chapter 3 and draws attention to the questions which should be asked and the available measures to deal with this important problem. A more specialised approach is adopted in considering pre-stressed cast iron vessels. Such structures differ considerably from traditional steel pressure vessels and so different design procedures are required. This is a novel approach and its use at present has been limited to very specific applications. Kemper, who considers vessels for food production, and has had great experience in this field, reviews the requirements for material selection and provision of internal coatings. Since such vessels may also be subjected

386 to external pressure loading, a discussion of a codified approach to design for such conditions is also included. The topic of external pressure is pursued in m ore detail by Kendrick where he discusses vessels for use when submerged in deep water, such as diving bells, submersibles and m a n y offshore structures. The final two chapters are concer ne d with pressure vessels which are subject to transportation, such m o v e m e n t producing its own peculiar problems. An authoritative review of the requirements for gas cylinder and c o n tain er design is given, emphasising the high level of quality assurance needed. In th e U.K. such vessels are subject to legislati.on and regulation and this aspect is discussed. Similar regulation surrounds vessels for road and rail t r a n s p o r t a t i o n and again the view in the U.K. is presented as an example of the features to be considered. Since most texts and reviews have c o n c e n t r a t e d on pressure vessels for conventional or nuclear power generation, this volume is a welcome edition in that it covers some of the less usual but nevertheless i m p o r t a n t ranges of vessels. The t r e a t m e n t is n o t t o o mathematical but blends aspects of the required stress analysis and codified procedures in a fashion which can be followed by the non-expert. This volume, as a single issue, should find wide readership and as part of the series on pressure vessel t echnol ogy extends the subject adequately.

Metallography Calendar 1986 T he decorative and artistically appealing micrographs which t h e Deutsche Gesellschaft ffir Metallkunde exhibits during t he Metallography Conference as part of a photographic c o m p e t i t i o n have given rise to the arrangement o f some o f these exhibits in a DGM calendar. T h e first calendar appeared in 1977 and has increased in popul a r i t y ever since. T h e DGM is planning a calendar for 1986 and is interested in receiving micrographs (colour only), either as slides (3.5 X 2.5 cm) or prints (approx. 22 X 16 cm -- ratio 100 : 70). Those interested can obtain f ur t her i nf orm at i on from: Deutsche Gesellschaft fiir Metallkunde e.V., Adenauerallee 21, D-6370 Oberursel/Taunus, West Ger man y . Tel. 0 6 1 7 1 / 4 0 8 1 .
