Using microwaves to treat metal-based materials is rapidly emerging
as an energy-efficient tool to interact with metals for a number of
processes such as sintering, melting, brazing, carburizing and
annealing. Microwaves can sinter a wide variety of metal compacts
with comparable or enhanced end properties, while at the same time
delivering tremendous energy savings over conventional sintering.
Microwave processes are therefore gaining increasing attention and
adoption in both academia and industry.
Gupta and Wong have written this comprehensive text to introduce
readers to the world of microwaves and the interaction of
microwaves with metals and metals-based formulations. The authors
have combined numerous research results from a wide range of
sources alongside their own work in the field. Also included are
overviews of microwave heating of other non-metal materials and the
equipment used for microwave-assisted metallurgy. With microwave
techniques poised for widespread adoption, Microwaves and
Metals is an essential text for all metallurgists and materials
engineers.
* Provides a thorough grounding in microwave fundamentals and
their application to metals processing
* Informs readers of the latest developments in the field
* Presents a convenient single source for all aspects of
microwave processing of metals and materials
* Contains liberal illustration to compare and benchmark research
results
* Introduces all the necessary equipment, preparing readers for
real-world practice
Microwaves and Metals is ideal for a post-graduate or
advanced undergraduate course in materials science or metallurgy.
Materials and metallurgical engineers in industry, who are keen on
cheaper, faster techniques, will also benefit from this book.
