Book Synopsis Nucleation and the Properties of Undercooled Melts by : L. Battezzati
Download or read book Nucleation and the Properties of Undercooled Melts written by L. Battezzati and published by Trans Tech Publications. This book was released on 2002 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of nucleation refers to the early stages of materials phase transformations in which a limited number of atoms or molecules are involved in the formation of seeds as a new phase originates from a matrix. Battezzati and Castellero (both: chemistry, U. of Torino, Italy) describe the theory of nucleation and discuss the thermophysical properties which mostly influence its rate. Although the material mostly focuses on classical theory starting from heterophase fluctuations, other theories are also described. Also included is a detailed analysis of quantities related to solidification. Annotation copyrighted by Book News Inc., Portland, OR.

This book was released on 2002-03-01 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nucleation is a central topic in Materials Science because it initiates most phase transformations. When a new phase appears within an existing phase, seeds must form before growth can occur within the given volume. The study of nucleation treats the very early stages, which involve only a limited number of atoms or molecules. It is a branch of fundamental research which has far-reaching implications for processes where nucleation is of paramount relevance to phase and microstructure selection. The development of any new material or processing route always leads to renewed interest in the topic.
Book Synopsis Solidification of Containerless Undercooled Melts by : Dieter M. Herlach
Download or read book Solidification of Containerless Undercooled Melts written by Dieter M. Herlach and published by John Wiley & Sons. This book was released on 2012-05-21 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: All metallic materials are prepared from the liquid state as their parent phase. Solidification is therefore one of the most important phase transformation in daily human life. Solidification is the transition from liquid to solid state of matter. The conditions under which material is transformed determines the physical and chemical properties of the as-solidified body. The processes involved, like nucleation and crystal growth, are governed by heat and mass transport. Convection and undercooling provide additional processing parameters to tune the solidification process and to control solid material performance from the very beginning of the production chain. To develop a predictive capability for efficient materials production the processes involved in solidification have to be understood in detail. This book provides a comprehensive overview of the solidification of metallic melts processed and undercooled in a containerless manner by drop tube, electromagnetic and electrostatic levitation, and experiments in reduced gravity. The experiments are accompanied by model calculations on the influence of thermodynamic and hydrodynamic conditions that control selection of nucleation mechanisms and modify crystal growth development throughout the solidification process.

Book Synopsis Science and Technology of the Undercooled Melt by : P.R. Sahm
Download or read book Science and Technology of the Undercooled Melt written by P.R. Sahm and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: "SCIENCE AND TECHNOLOGY OF '!HE UNDEROLED MELT" This title was chosen as the topical headline of the Advanced Research Workshop (ARW) from March 17 to 22 1985, held at the Castle of Theuern. The usual term "Rapid Solidification" is an overlapping description. Due to the fact that nucleation is so eminently important for the undercooling of a melt and this, in turn, is an important characteristic of rapid solidifi cation, undercooling plays an essential role in "rapid solidification." The undercooled melt has caused an "accelerated evolution" (if not a revolution) in materials science during the last decade. Several rather exciting concepts with interesting potential for novel applications are being pursued presently in various laboratories and companies. They concern not only new processes and ha~ware developments, but also present chal lenging perspectives for ventures, including the founding of new companies; or they promise growth possibilities with established larger and smaller industrial establishments.

Book Synopsis Nucleation in Condensed Matter by : Ken Kelton
Download or read book Nucleation in Condensed Matter written by Ken Kelton and published by Elsevier. This book was released on 2010-03-19 with total page 759 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Nucleation in Condensed Matter, key theoretical models for nucleation are developed and experimental data are used to discuss their range of validity. A central aim of this book is to enable the reader, when faced with a phenomenon in which nucleation appears to play a role, to determine whether nucleation is indeed important and to develop a quantitative and predictive description of the nucleation behavior. The third section of the book examines nucleation processes in practical situations, ranging from solid state precipitation to nucleation in biological systems to nucleation in food and drink. Nucleation in Condensed Matter is a key reference for an advanced materials course in phase transformations. It is also an essential reference for researchers in the field. - Unified treatment of key theories, experimental evaluations and case studies - Complete derivation of key models - Detailed discussion of experimental measurements - Examples of nucleation in diverse systems

This book was released on 2012-12-06 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents a collection of papers presented at the NATO Advanced Research Workshop (NATO/ARW) on "Science and Technology of Rapid Solidification and Processing", held at Hotel Thayer, West Point Military Academy, New York, N. Y. , during June 21-24, 1994. The workshop was attended by over forty scientists representing several NATO member countries as well as representatives from Japan, China (PRC), Taiwan and India. The purpose of this NATO/ARW conference was to review the major advances made in most recent years in both the theoretical and experimental areas of rapid solidification technology and processing. In accordance with the NATO/ARW format, the agenda for the conference was so arranged to offer in depth presentation of the latest developments in the subject area as well as to encourage follow-up discussions by the participants. There was seven sessions each opened with a lecture by an invited guest speaker. Sessions 1-4, covered two days of the conference and focused mainly on Processing Technologies of Rapid Solidification and Thermodynamic Properties (Practical Applications). Sessions 4-6 concentrated on Thermodynamics of Metastable Alloys, Relaxation, Diffusion, Magnetic and Electric Properties (Fundamentals). Session 6 was devoted to the Structural Characterization of Supercooled Melts, Ultra Fine Polycrystalline Materials (New Innovations and Techniques). There were two equally important aspects of this NATO/ARW conference which must be mentioned. Firstly, this is the first NATO/ARW conference on Science and Technology of Rapid Solidification and Processing held in the United States.
