This book was released on 1973 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nous nous sommes intéressés au système fer-platine qui, pour des compositions voisines de la composition stoechiométriques Fe3Pt, présente, suivant la température, tois transformations distinctes : une transformation ordre-désordre, une transformation magnétique et une transformation martensitique. Nous avons abordé ce travail avec l'intention d'étudier ces trois transformations en nous attachant, plus particulièrement, à mettre en évidence la manière suivant laquelle elles s'influent mutuellement. Nous nous sommes attardés, plus particulièrement, à l'influence de l'état d'ordre initial de l'austénite sur la transformation martensitique. Nous avons rassemblé, dans le chapitre I, l'aspect théorique de la transformation ordre-désordre, l'élaboration des alliages et des techniques expérimentales. Dans le chapitre II, nous présentons l'étude radiocristallographique de la transformation ordre-désordre en mettant en évidence le fait que les techniques de diffraction et de diffusion des rayons X ne permettent pas, à elles seules, d'élucider le mécanisme de transformation ordre-désordre. Le chapitre III est plus particulièrement consacré à l'étude de quelques aspects de la transformation martensitique en relation avec l'état d'ordre initial de l'austénite. Cette étude nous a permis, grâce à l'observation de la transformation martensitique aux basses températures, de montrer que la transformation ordre-désordre de l'austénite est régie par un mécanisme de premier ordre.

This book was released on 2012-12-06 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: When considering the operational performance of stainless steel weldments the most important points to consider are corrosion resistance, weld metal mechanical properties and the integrity ofthe weldedjoint. Mechanical and corrosion resistance properties are greatly influenced by the metallurgical processes that occur during welding or during heat treatment of welded components. This book is aimed, there fore, at providing information on the metallurgical problems that may be encountered during stainless steel welding. In this way we aim to help overcome a certain degree of insecurity that is often encountered in welding shops engaged in the welding of stainless steels and is often the cause of welding problems which may in some instances lead to the premature failure of the welded component. The metallurgical processes that occur during the welding of stainless steel are of a highly intricate nature. The present book focuses in particular on the signif icance of constitution diagrams, on the processes occurring during the solidification of weld metal and on the recrystallization and precipitation phenomena which take place in the area of the welds. There are specific chapters covering the hot cracking resistance during welding and the practical welding of a number of different stainless steel grades. In addition, recommendations are given as to the most suitable procedures to be followed in order to obtain maximum corrosion resistance and mechanical properties from the weldments.

Available in PDF, EPUB and Kindle. Book excerpt: Lasers can alter the surface composition and properties of materials in a highly controllable way, which makes them efficient and cost-effective tools for surface engineering. This book provides an overview of the different techniques, the laser-material interactions and the advantages and disadvantages for different applications. Part one looks at laser heat treatment, part two covers laser additive manufacturing such as laser-enhanced electroplating, and part three discusses laser micromachining, structuring and surface modification. Chemical and biological applications of laser surface engineering are explored in part four, including ways to improve the surface corrosion properties of metals. - Provides an overview of thermal surface treatments using lasers, including the treatment of steels, light metal alloys, polycrystalline silicon and technical ceramics - Addresses the development of new metallic materials, innovations in laser cladding and direct metal deposition, and the fabrication of tuneable micro- and nano-scale surface structures - Chapters also cover laser structuring, surface modification, and the chemical and biological applications of laser surface engineering
