1. Edition October 2009
456 Pages, Hardcover
Wiley & Sons Ltd
The most up-to-date coverage of welding metallurgy aspects and
weldability issues associated with Ni-base alloys
Welding Metallurgy and Weldability of Nickel-Base Alloys
describes the fundamental metallurgical principles that control the
microstructure and properties of welded Ni-base alloys. It serves
as a practical how-to guide that enables engineers to select the
proper alloys, filler metals, heat treatments, and welding
conditions to ensure that failures are avoided during fabrication
and service. Chapter coverage includes:
* Alloying additions, phase diagrams, and phase stability
* Solid-solution strengthened Ni-base alloys
* Precipitation strengthened Ni-base alloys
* Oxide dispersion strengthened alloys and nickel aluminides
* Repair welding of Ni-base alloys
* Dissimilar welding
* Weldability testing
* High-chromium alloys used in nuclear power applications
With its excellent balance between the fundamentals and
practical problem solving, the book serves as an ideal reference
for scientists, engineers, and technicians, as well as a textbook
for undergraduate and graduate courses in welding metallurgy.
