Volume 15 of the 9th Edition, a stand-alone volume on the subject, is evidence of the strong commitment of ASM International to the advancement of casting technology. The decision to devote an entire Handbook to the subject of casting was based on the veritable explosion of improved or entirely new molding, melting, metal treatment, and casting processes that has occurred in the 18 years since the publication of Volume 5. New casting materials, such as cast metal-matrix composites, also have been developed in that time, and computers are being used increasingly by the foundry industry.
An entire section of this Handbook is devoted to the application of computers to metal casting, in particular to the study of phenomena associated with the solidification of molten metals.
Coverage of the depth and scope provided in Volume 15 is made possible only by the collective efforts of many individuals. In this case, the effort was an international one, with participants in 12 nations.
The driving force behind the entire project was volume chairman Doru M. Stefanescu of the University of Alabama, who along with his section chairmen recruited more than of the leading experts in the world to author articles for this Handbook.
We are indebted to all of them, as well as to the members of the ASM Handbook Committee and the Handbook editorial staff. Their hard work and dedication have culminated in the publication of this, the most comprehensive single-volume reference on casting technology yet published.
William G. Langer Managing Director, ASM International Preface The story of metal casting is as glamorous as it is ancient, beginning with the dawn of human civilization and interwoven with legends of fantastic weapons and exquisite artworks made of precious metals. Science of casting and solidification is a major technical asset for foundry operations and of extreme importance in understanding different length scales microstructural changes and evolution as well as developing new processes and materials.
In his attempt to describe combinations of solidification theory, research results and industrial practice, Professor Doru Michael Stefanescu ASM Fellow, has made tremendous contributions to the field. Many of his views on casting and solidification are valued as important impacts within professional environments such as TMS and ASM International.
He has written many articles for the ASM Handbook series on subjects including basic metallurgy of cast iron, compacted graphite irons, solidification, thermodynamic properties of iron-base alloys, and computational modeling. He was also Volume Chair for Volume Casting , of the 9 th Edition Metals Handbook. Unable to display preview. Download preview PDF. Skip to main content.

The other, developed for iron and steel casting is the FM process. The Cosworth process was developed to meet the need for highly specialized components for the Formula One racing car engines manufactured by Cosworth Engineering, Ltd.
Zircon sand molds with a furan binder system are filled from the bottom of the mold by using an electromagnetic pump.
A vertical launder is located in the middle of a holding furnace, and it moves the metal at a controlled rate into the rigid sand mold. Locating the filling tube in the middle of the furnace helps ensure that only the cleanest metal enters the mold, thus reducing the possibility of slag or dross entering the mold cavity. With a blanket of inert gas covering the molten metal in the furnace, the molten aluminum is protected from oxygen and other gases that may lead to porosity in the casting.
In addition, because the mold fill rate is closely controlled, turbulence is minimized, and this also prevents the pickup of oxygen and other gases that may lead to porosity. Several American foundries are in the process of adopting or seriously investigating the Cosworth process for their aluminum casting operations.
The FM process has been specifically developed to produce thin-wall iron and steel casting Ref 6. The name FM comes from fonte mince, meaning thin iron. Developed and used by the French firm Pont-a-Mousson, the FM process is a mold filling technique versus mold pouring that utilizes a controlled differential pressure to fill molds with high-melting metals, including superalloys. Like the Cosworth process, the FM process utilizes a bottom filling technique that is controlled and yet allows for rapid filling of the mold.
Any type of mold green sand, metal, shell, and so on can be used with the FM process. The rapid fill rates are achieved by exerting a low pressure on the liquid metal and a negative pressure on the mold and, in certain cases, on the furnace itself.
