Fundamentals of Die Casting Design.pdf
Taken from Abstract: Die-casting engineers have to compete not only with other die-casting companies, but also against other industries such as plastics, and composite materials. Clearly, the ”black art” approach, which has been an inseparable part of the engineer’s tools, is in need of being replaced by a scientific approach. Excuses that “science has not and never will work” need to be replaced with “science does work”. All technologies developed in recent years are described in a clear, simple manner in this book. All the errors of the old models and the violations of physical laws are shown. For example, the “common” pQ2 diagram violates many physical laws, such as the first and second laws of thermodynamics. Furthermore, the “common” pQ2 diagram produces trends that are the opposite of reality, which are described in this book.
The die casting engineer’s job is to produce maximum profits for the company.
In order to achieve this aim, the engineer must design high quality products at a minimum cost. Thus, understanding the economics of the die casting design and process are essential. These are described in mathematical form for the first time in this volume. Many new concepts and ideas are also introduced. For instance, how to minimize the scrap/cost due to the runner system, and what size of die casting machine is appropriate for a specific project.
The die-casting industry is undergoing a revolution, and this book is part of it. One reason (if one reason can describe the situation) companies such as Doehler Jorvis (the biggest die caster in the world) and Shelby are going bankrupt is that they do not know how to calculate and reduce their production costs. It is my hope that die-casters will turn such situations around by using the technologies presented in this book. I believe this is the only way to keep the die casting professionals and the industry itself, from being “left in the dust.”
Fundamentals of Air Pollution Engineering.pdf
Taken from Preface: Analysis and abatement of air pollution involve a variety of technical disciplines. Formation of the most prevalent pollutants occurs during the combustion process, a tightly coupled system involving fluid flow, mass and energy transport, and chemical kinetics. Its complexity is exemplified by the fact that, in many respects, the simplest hydrocarbon combustion, the methane-oxygen flame, has been quantitatively modeled only within the last several years. Nonetheless, the development of combustion modifications aimed at minimizing the formation of the unwanted by-products of burning fuels requires an understanding of the combustion process. Fuel may be available in solid, liquid, or gaseous form; it may be mixed with the air ahead of time or only within the combustion chamber; the chamber itself may vary from the piston and cylinder arrangement in an automobile engine to a lO-story-high boiler in the largest power plant; the unwanted byproducts may remain as gases, or they may, upon cooling, form small particles.
The Thermodynamics of Phase Equilibrium.pdf
Taken from Introduction: This paper is the first in a series in which thermodynamics is developed beyond its usual scope from a new postulational basis. The postulational basis of classical thermodynamics is firmly established in tradition and a new departure calls for an explanation of the underlying ideas. It is widely believed that thermodynamics consists essentially of the implications of the first, second, and third law of thermodynamics. Actually, however, few if any significant results can be derived from these postulates without using a number of additional assumptions concerning the properties of material systems, such as the existence of homogeneous phases, validity of equations of state and the like.

Titanium - Design and Fabrication Handbook for Industrial Applications.pdf
Titanium offers an excellent combination of mechanical properties and corrosion resistance. These features, coupled with availability of product forms and ease of fabrication, have led to extensive use of titanium and its alloys in chemical process equipment. Titanium is now a standard material of construction for many chemical processes and equipment, and systems are being assembled by a variety of fabricators on a routine basis for use in many other industries.
