This book was released on 2002 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: La forte interdépendance entre les traitements thermomécaniques d'élaboration et les propriétés des métaux (e.g. ductilité ou résistance mécanique) amène à décrire les métaux par les caractéristiques de l'agrégat polycristallin (caractéristiques microstructurales et texture cristallographique). Au cours du laminage à chaud des alliages d'aluminium, la fragmentation des grains en sous-grains (contrôlée par les phénomènes métallurgiques d'écrouissage et de restauration dynamique), est un paramètre clé des évolutions de ces caractéristiques, mais pour lequel il manque une description quantitative. Ce travail de thèse répond à cette attente, en apportant, par l'acquisition de cartes d'orientations locales par EBSD, une caractérisation précise des sous-structures de compression plane à chaud (" channel-die " [sigma]=10-3/10-1/1/10 s-1, T=400/450/500ʿC, sigma=75%) de monocristaux d'alliage Al-1%Mn (orientations typiques des composantes textures de laminage à chaud, cube {001}100, Laiton {110}112, Cuivre {112}111, mais aussi U {110}110). L'influence de l'orientation des monocristaux se traduit par 3 types de microstructures : 1 - Stable (sous-structure et sous-texture homogène : Orientation Laiton et U). 2 - Instable (formation de bandes de déformation : orientation Cuivre). 3 - Métastable (sous-structure et sous-texture hétérogène : orientation cube). Pour les orientations stables, l'influence des conditions de déformation, se traduit par une relation linéaire entre le paramètre de Zener-Hollomon Z et l'intercept moyen. De plus, une approche statistique originale qui décrit quantitativement les étalements des sous-textures (distribution des orientations intragranulaires), montre le comportement de type LEDs (" Low Energy Dislocation structures ") des orientations stables. Pour l'orientation cube, la microstructure est hétérogène, avec une forte différence de taille des sous-grains suivant les zones. Cette hétérogénéité diminue avec la diminution de Z.

Available in PDF, EPUB and Kindle. Book excerpt: Reviewing an extensive array of procedures in hot and cold forming, casting, heat treatment, machining, and surface engineering of steel and aluminum, this comprehensive reference explores a vast range of processes relating to metallurgical component design-enhancing the production and the properties of engineered components while reducing manufacturing costs. It surveys the role of computer simulation in alloy design and its impact on material structure and mechanical properties such as fatigue and wear. It also discusses alloy design for various materials, including steel, iron, aluminum, magnesium, titanium, super alloy compositions and copper.

Download or read book Dictionnaire International de Froid written by International Institute of Refrigeration and published by Peeters Publishers. This book was released on 2007 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: The English-French volume of the International Dictionary of Refrigeration contains approximately 4400 terms with their definitions in the 2 official languages of the International Institute of Refrigeration, English and French. Approximately 200 experts, who are members of the IIR network and are from about 30 countries on all the continents, took part in the development of the Dictionary. The terms are allocated to 11 chapters: Fundamentals - Refrigeration and Production - Refrigerating Equipment - Cooling Methods - Storage, Transport, Distribution - Refrigeration of Perishable Products - Air Conditioning - Heat Pumps - Cryology - Other Applications of Refrigeration - Refrigeration and the Environment. The terms are classified in alphabetical order within 110 sections. An alphabetical index in English and another one in French make it easy to perform searches for terms and their synonyms. 9 volumes will be published containing the terms alone in 9 languages, with the corrresponding English and French equivalents: Arabic, Chinese, Dutch, German, Italian, Japanese, Norwegian, Russian and Spanish.(Now published) Le volume anglais-francais du Dictionnaire International du Froid comporte environ 4400 termes avec leurs definitions dans les deux langues officielles de l'Institut International du Froid (IIF). Pres de 200 experts, membres du reseau de l'IIF, appartenant a une trentaine de pays de tous les continents, ont participe a l'elaboration du Dictionnaire. Les termes sont regroupes dans 11 chapitres: Principes de base - Production de froid - Installations frigorifiques - Methodes de refroidissement - Entreposage, transport, distribution - Application du froid aux produits perissables - Conditionnement d'air - Pompes a chaleur - Cryologie - Autres applications du froid - Froid et environnement. Les termes sont classes par ordre alphabetique en anglais dans 110 sous-chapitres. Deux index alphabetiques, en anglais et en francais, permettent de trouver rapidement les termes cherches et leurs synonymes. Neuf fascicules vont etre publies avec uniquement les termes en neuf langues, en correspondance avec les termes anglais et francais : allemand, arabe, chinois, espagnol, italien, japonais, neerlandais, norvegien et russe (publies).

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the Proceedings of the Twelfth International Congress of Applied Mechanics, held at Stanford University on August 26 to 31, 1968. The Congress was organized by the International Union of Theoretical and Applied Mechanics; members of the IUTAM Congress Committee and Bureau are listed under Congress Organization. The members of the Stanford Organizing Committee, which was responsible for the detailed organization of the Congress, are also given, as are the names of the sponsors and the industrial and educational organizations that contributed so generously to the financial support of the meeting. Those attending the Congress came from 32 countries and totaled 1337 persons, plus wives and children. A list of the registered participants is included in the volume. The technical sessions of the Congress comprised four General Lectures and 281 contributed papers, the latter being presented in groups of five simultaneous sessions. The final choice of the contributed papers was made on the basis of abstracts by an International Papers Commit tee of IUTAM consülting of G. K. BATCHELOR, E. BECKER, N. J. HOFF, and W. T. KOlTER.
