Presents all the main aspects of the microstructure of nickel-base superalloys, and includes micrographs chosen from among a large range of commercial and academic alloys, from the as-cast product to in-situ components, worn from in-service use. Including more than 100 illustrations, the text explains all the transformation mechanisms involved in the origination (creation) of microstructures during solidification or heat treatments (crystallization paths, segregation, crystal orientation, precipitation, TCP, coarsening and rafting, etc.). It includes up-to-date information and data such as phase diagrams, crystallographic structures, and relationships with functional properties. Nearly 300 references provide a key to further investigation.

Qu'est-ce qu'un superalliage Un superalliage, ou alliage haute performance, est un alliage capable de fonctionner à une fraction élevée de son point de fusion. Plusieurs caractéristiques clés d'un superalliage sont une excellente résistance mécanique, une résistance à la déformation par fluage thermique, une bonne stabilité de surface et une résistance à la corrosion ou à l'oxydation. Comment vous en bénéficierez (I) Insights et validations sur les sujets suivants : Chapitre 1 : Superalliage Chapitre 2 : Alliage renforcé par dispersion d'oxyde Chapitre 3 : Aluminiure de titane Chapitre 4 : Alliage Chapitre 5 : Résistance des matériaux Chapitre 6 : Fluage (déformation) Chapitre 7 : Corrosion Chapitre 8 : Rédox (II) Répondre aux principales questions du public sur les superalliages. (III) Exemples concrets d'utilisation du superalliage dans de nombreux domaines. (IV) 17 annexes pour expliquer, brièvement, 266 technologies émergentes dans chaque industrie pour avoir une compréhension complète à 360 degrés des technologies de superalliages. À qui s'adresse ce livre Professionnels, étudiants de premier cycle et diplômés, passionnés, amateurs et ceux qui veulent aller au-delà des connaissances ou des informations de base pour tout type de superalliage.

A superalloy, or high-performance alloy, is an alloy that exhibits excellent mechanical strength at high temperatures. Superalloy development has been driven primarily by the aerospace and power industries. This compilation of papers from the Twelfth International Symposium on Superalloys, held from September 9-13, 2012, offers the most recent technical information on this class of materials.

This volume contains the edited version of lectures and selected research contributions presented at the NATO ADVANCED STUDY INSTITUTE on MECHANICAL BEHA VI OUR OF MATERIALS AT HIGH TEMPERATURE, held in Sesimbra, Portugal, 12th-22nd September 1995, and organized by 1ST-Lisbon Institute of Technology, PortugaL The Institute was attended by 88 participants, including 15 lecturers from 17 countries including five CP countries. The lecturers were leading scientists and technologists from universities, research institutions and industry. The students were mainly young PhD students and junior academic or research staff with postgraduate qualifications (MSc or PhD). Fourteen students were from the five CP countries. The students presented research papers or posters during the Institute reporting the current progress of their research projects. A total of thirty three lectures, ten research papers and fifty posters were presented. This book does not contain the poster presentations and seven research papers were selected for publication. All the sessions were very active and quite extensive discussions on scientific aspects took place during the Institute. The Advanced Study Institute provided a forum for interaction among scientists and engineers from different areas of research, and young researchers.

Over the last forty years a wide range of surface coatings have been developed to address the surface stability and thermal insulation of materials used in the gas turbine section of aero, industrial and land-based power generation equipment. High Temperature Surface Engineering, the Proceedings of the Sixth International Conference in the Series ‘Engineering the Surfaces’, reviews the surfacing technologies appropriate to oxidation, corrosion and thermal protection. Factors which underpin their choice for any given application are discussed in the proceedings. This highlights the importance of developing representative mechanical and physical test methods to elucidate coating degradation modes as an aid to establishing coating systems with improved engineering performance. During the organisation of the conference and in the compiling of this book we have been privileged to work with many of the leading specialists in the field of High Temperature Surface Engineering and it is our hope that this book will be a valuable reference guide for Engineers and Material Scientists.
