Book Description
Powder Metallurgy of Superalloys details the advancement of powder metallurgy in the context of producing superalloys. The book is comprised of nine chapters that cover the underlying principles of superalloys produced through powder metallurgy. The text first covers concerns in pre-alloyed dispersion-free powders, such as powder production and characterization; powder consolidation methods; and quality control and non-destructive evaluation of P/M superalloys. The next chapter talks about oxide-dispersion-strengthened superalloys. Next, the book discusses joining techniques for P/M superalloys and the practical applications of P/M superalloys. The title will be of great use to professionals in the materials manufacturing industry.

Book Description
Aluminum P/M parts can be production sintered in various types of furnaces and atmospheres. Selection of sintering furnace depends upon economic considerations and production rates desired. Batch furnaces have lowest investment costs and are adequate for low to medium production whereas continuous furnaces are more costly but provide higher production rates. strong, well-sintered P/M parts can be obtained in atmos pheres of nitrogen, dissociated ammonia and in vacuum. Atmos phere selection depends upon facilities available within individual plants plus property requirements. Highest strengths are produced in nitrogen followed by vacuum and dissociated ammonia. Repro ducible dimensions can be achieved with proper attention to com pact density, sintering temperature, dew point and atmosphere. REFERENCES 1. J. H. Dudas and W. A.

Book Description
Substantial increases in raw material and labor costs have provided the impetus for many diverse investigations aimed at reducing the manufacturing costs of aircraft gas turbine hardware. One of the most significant programs conducted at General Electric during the past decade involves application of powder metallurgy (P/M) processing technology to the fabrication of nickel-base superalloy rotating components. The evolution of P/M technology and its application to a high-strength superalloy, René 95, in a number of diverse aircraft engine components is described. Initial development concentrated on fabrication of P/M hardware by hot isostatic pressing (HIP) cylindrical powder preforms and forging in a conventional die system to an oversize shape. Subsequent refinement of this HIP plus forge process included HIP for shaped preforms followed by forging in an isothermal die system to a near net shape.
