We come to know about the world in two distinctive ways: by direct perception and by application of rational reasoning which, in its highest form, is mathematical thinking. The belief that the underlying order of the world can be expressed in mathematical form lies at the very heart of science. In other words, we only know what we can describe through mathematical models. Casting of metals has evolved first as witchcraft, to gradually become an art, then a technology, and only recently a science. Many of the processes used in metal casting are still empirical in nature, but many others are deep-rooted in mathematics. In whatever form, casting of metals is an activity fundamental to the very ...
Adopting a holistic approach to materials simulation, this monograph covers four very important structural materials: aluminum, carbon steels, superalloys, and plastics. Following an introduction to the concept of integral modeling, the book goes on to cover a wide range of production steps and usage, including melt flow and solidification behavior, coating, shaping, thermal treatment, deep drawing, hardness and ductility, damage initiation, and deformation behavior.
The proceedings of a symposium held in Berlin in March 1996, drawing together practical expertise in measurement techniques, with typical applications ranging from in situ measurements of strain and rotation on small specimens through notched specimens and single crystal up to turbine blade shaped samples and full scale component testing. The symposium also highlighted new techniques such as speckle interferometry and image analysis.
Rapidly Quenched Metals 6, Volume 1 covers the proceedings of the Sixth International Conference on Rapidly Quenched Metals held at Le Centre Sheraton, Montreal, Canada from August 3 to 7, 1987. The said conference discusses a wide variety of topics in the field of rapidly solidified metals. The book is divided into two parts. Part 1 covers topics that involve the formation and transformation in metallic materials; amorphous metals; the applications of mechanical alloying; and rapid melting and quenching. Part 2 discusses the formation and structure of amorphous alloys, which includes topics such as the metastability of amorphous phases; amorphous alloy powders; and studies about the properties of different amorphous alloys. The text is recommended for those involved in materials science and metallurgy, especially those studying rapidly solidified metals and amorphous alloys.
The aim of this major reference work is to provide a first point of entry to the literature for the researchers in any field relating to structural integrity in the form of a definitive research/reference tool which links the various sub-disciplines that comprise the whole of structural integrity. Special emphasis will be given to the interaction between mechanics and materials and structural integrity applications. Because of the interdisciplinary and applied nature of the work, it will be of interest to mechanical engineers and materials scientists from both academic and industrial backgrounds including bioengineering, interface engineering and nanotechnology. The scope of this work encomp...
In a career spanning almost six decades, Prof. John T. Berry has made significant contributions towards building our understanding of solidification and process-structure-property relationships in shaped castings. Celebrating his contributions, the Fourth International Shape Casting Symposium, which takes place at the 2011 TMS Annual Meeting & Exhibition, has been organized in his honor. Shape Casting 2011 contains the proceedings of the symposium in which scientists and engineers from around the world presented their own research findings, discussed challenges in the field, and projected future directions. Papers explore such topics as liquid metal quality; filling and feeding systems; process modeling for shaped castings; structure-property relationships; performance of shaped castings; and machinability of castings.
The phase transformation from liquid to solid is a phenomenon central to a wide range of manufacturing and natural processes. The presence of phase transformation can drive convection in the melt through the liberation of latent heat, the rejection of solute, and the change of density upon freezing. The fluid mechanics itself can playa central role; the phase transformation can be strongly altered by convective transport in the liquid through the modification of the thermal and solutal environment of the solid-liquid interface; these local fields control the freezing characteristics at the interface. The convection can be generated naturally by buoyancy forces arising from gradients of tempe...
100 years after the first observation of ripening by Ostwald and 40 years after the first publication of a theory describing this process, this monograph presents in a self-consistent and comprehensive manner, all the bits and pieces of coarsening theories so that the main issues and the underlying mathematics of self-similar coarsening of dispersed systems can be understood. Rather than giving a complete survey of the field, it presents a careful derivation of the existing results and places them into some perspective.
