Numerous industrial users were asked for their appraisal of vacuum-degassed steel. Their responses regarding the merits of this vacuum treatment were varied. The producers and users of large forgings reported fewer internal defects, improved toughness, and decreased processing time through shorter hydrogen relief treatments. Improved fatigue life in applications such as bearings was attributed to fewer and smaller nonmetallic inclusions in vacuum-degassed steel. The users of medium and small forgings reported only marginal improvement in properties and little or no change in rejection rates by nondestructive testing. Unfortunately, many of the users could not give a meaningful evaluation because they knew that frequently their suppliers filled orders with vacuum-degassed steels even though such treatment was not specified. Consequently, these users are unable to separate the air melted and the vacuum-degassed steels in their stock for comparison. A more comprehensive study of fully identified steels, steelmaking practice, degassing methods, material properties, and performance in service will be required before a satisfactory evaluation of the merits of vacuum-degassed steels can be made.

This report gives the experiences of several steel producers and consumers with vacuum degassing as a melting practice in the manufacture of high-strength steels for critical applications. The parameters involved in determining the effects of melting practice on mechanical properties are outlined. Pertinent melting processes are described and evaluated qualitatively. In presenting the data, vacuum degassing is compared with other melting practices such as conventional air melting and consumable-electrode vacuum-arc remelting (CEVAR). Generally, there is a trend indicating that vacuum degassing is being used in some production applications instead of air-melted or CEVAR material. In terms of higher and more uniform transverse tensile properties and impact strength, longer fatigue life, and improved cleanliness, the CEVAR alloys were the best. Vacuum degassing by any of the various methods resulted in an improvement in properties of air-melted alloys. In some instances it appeared that the quality of CEVAR alloys could be approached when stream degassing or D-H (Dortmund-Horder) treatment was applied to air melts. Recommendations are given for additional investigations on the effects of melting practice on mechanical properties of premium-quality steels. (Author).

Recrystallization shows selected results obtained during the last few years by scientists who work on recrystallization-related issues. These scientists offer their knowledge from the perspective of a range of scientific disciplines, such as geology and metallurgy. The authors emphasize that the progress in this particular field of science is possible today thanks to the coordinated action of many research groups that work in materials science, chemistry, physics, geology, and other sciences. Thus, it is possible to perform a comprehensive analysis of the scientific problem. The analysis starts from the selection of appropriate techniques and methods of characterization. It is then combined with the development of new tools in diagnostics, and it ends with modeling of phenomena.

STEELS: Metallurgy and Applications provides a metallurgical understanding of commercial steel grades and the design, manufacturing and service requirements that govern their application. The properties of different steels are described, detailing the effect of composition, processing and heat treatment. Where appropriate an introduction is given to standard specifications and design codes provided on component manufacture and property requirements for successful service performance. The book deals with steel products in some depth, in four chapters covering wide strip, structural steels, engineering and stainless steel grades. At the begining of each chapter an overview is given which details important features of the grades and a historical perspective of their development. Also featured are up to date information on steel prices and specifications. David Llewellyn has over thirty years experience in the steel industry and is currently lecturing in the Materials Engineering Department at University College Swansea. '..the book unfolds into an easily readable and a valuable source of highly relevant and contemporary information on steels' - METALS AND MATERIALS '.. a high quality product from all points of view' - INSTITUTE OF METALS AND MATERIALS AUSTRALASIA features up to date information on steel prices and specifications.
