Much of the world's recent research and development on metallic foams and porous metals is contained in this fully refereed book. The book's chapters were developed from the International Conference held in 2007 in Montreal, Canada. This comprehensive volume explains new ways to design and process metallic foams, including many non-aluminum foams, and illustrates the numerous industry applications where metallic foams and porous metals are being implemented. Metallic foams are relatively new materials that offer opportunities in a wide range of applications. Specific applications include: lightweight auto parts, orthopedic and dental implants, sound absorbers, filters, heat exchangers, electrodes, catalyst supports - and many more. This title contains over 100 original, never published, refereed chapters on metallic foams and porous metals, and new work on nickel and steel foams, titanium, and nanoporous gold. It covers materials engineering, design, properties and characterization. It also features dozens of new applications for automotive, biomaterials, orthopedics, thermal technology, filtration, and electrochemistry.
