Superalloys: A Technical Guide, 2nd EditionASM International, 2002 M01 1 - 439 pages This book covers virtually all technical aspects related to the selection, processing, use, and analysis of superalloys. The text of this new second edition has been completely revised and expanded with many new figures and tables added. In developing this new edition, the focus has been on providing comprehensive and practical coverage of superalloys technology. Some highlights include the most complete and up-to-date presentation available on alloy melting. Coverage of alloy selection provides many tips and guidelines that the reader can use in identifying an appropriate alloy for a specific application. The relation of properties and microstructure is covered in more detail than in previous books. |

Page vii - HOW happy is he born and taught That serveth not another's will; Whose armour is his honest thought, And simple truth his utmost skill ! Whose passions not his masters are; Whose soul is still prepared for death, Untied unto the world by care Of public fame or private breath; Who envies none that chance doth raise...

Page 174 - FRICTION WELDING is a process in which the heat for welding is produced by direct conversion of mechanical energy to thermal energy at the interface of the workpieces without the application of electrical energy, or heat from other sources, to the workpieces.
Page 104 - ... steps. Forging conditions (temperature and reduction) have a significant effect on the grain size of cobalt-base alloys. Because low ductility, notch brittleness, and low fatigue strength are associated with coarse grains, close control of forging and of final heat treatment is important. Cobaltbase alloys are susceptible to grain growth when heated above about 1175 °C (2150 °F).
Page 137 - Udimel 700 and Inconel X-750, because water quenching causes cracking. However, for complex shapes subject to excessive distortion, oil quenching is often adequate and more practical. Rapid air cooling usually is adequate for parts formed from strip or sheet.
Page 180 - It should not be used in a pure dry hydrogen atmosphere, because it will cause carburization of the base metals by gaseous transfer. Molybdenum and tungsten may be used, but they are generally avoided because of their cost. Controlled Atmospheres. Controlled atmospheres (including vacuum) are used to prevent the formation of oxides during brazing and to reduce the oxides present so that the brazing filler metal can wet and flow on clean base metal. Controlled atmosphere brazing is widely used for...
