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.”
The Welding Handbook for Maritime Welders.pdf
Taken from Solutions: Problem Steel: Among the low alloy steels, there is also a large group of special steels with complicated chemical composition. These include spring steel, vanadium steel, high speed steel, tool steel, etc. All these steel types are difficult to weld. In many cases the steel has been hardened by annealing, and welding can destroy the hardening.
In principle, all these steels can be welded with matching ferritic consumables with the aid of preheating and postweld heat treatment to avoid hydrogen cracking in the heat affected zone (HAZ).
In the case of repair welding, it is, however, often not possible to preheat or to perform any postweld heat treatment.
So, in this case, welding with austenitic stainless or nickel-based consumables is considered to be one of the best methods. The risk of cracking is reduced by the higher solubility of hydrogen and the greater ductility of the weld metal.
There are so many types of low alloy steel on the market today that even specialists have difficulty in keeping track of the entire range. Numerous types of special alloys not classified under existing standards, are marketed by the steel works. Most types can be welded satisfactorily with Unitor Tensile having a tensile strength of 850 N/mm2. This electrode may be used both for joining and for building-up work

2005 Organic Chemistry Laboratory Manual.pdf
Taken from Introduction: Organic Chemistry is a fascinating field. Think about it, of roughly 110 elements on the periodic charts, organic chemistry is a discipline that deals primarily with just one of these element: carbon. And the element is so versatile and important, that organic compounds are the largest group of compounds, far outnumbering compounds made from every other element on the periodic chart. In your study of organic chemistry, remember that you are starting on the ground floor of the chemistry of life. This is where the term of organic comes from: there was a belief that organic compounds could only come from the action of living organisms (the vitalism theory, one of the more famous failures to survive the test of time). The earliest chemists would categorize compounds into organic and other (or more appropriately inorganic). Now even though we know that organic compounds can be made from inorganic compounds synthetically, the chemistry of carbon is so closely related to metabloic processes that many of these same mechanisms and reactions are used by your body.
