A look at the current and future uses of magnesium-based products
and their role in the world’s environmental and technological
revolution
The lightest of all structural metals, having one-fourth the
density of steel and two-thirds that of aluminum, magnesium has
already been adopted as an alternative construction material in
applications as far ranging as automotive and sports equipment,
electronics, and space technology. In a world concerned with
minimizing the environmental impact of products, the choice of
light-weight, energy-saving, and high-performance materials, like
magnesium, would seem a small, significant step towards improving
life on this planet. Magnesium, Magnesium Alloys, and Magnesium
Composites introduces the science and current applications of this
important metal, shedding light on the magnesium-based composites
developed over the last fifteen years. Chapters include in-depth
discussion of:
* The characteristics of pure magnesium–including atomic
properties and crystal structure as well as physical, electrical,
and mechanical properties
* Magnesium alloys–and the effects of the alloying elements,
such as aluminum, lithium, copper, nickel, and silicon
* The properties of magnesium-based composites–and the
effects of different types (metallic, ceramic, interconnected, and
intermetallic) of reinforcements of varying length (from micron
scale to nanometric length)
* Corrosion aspects of magnesium-based materials
* Magnesium-based products in medicine, sports equipment, and the
automotive, aerospace, and electronics industries
Bringing together, for the first time, the science, properties,
and technologies relating to the current and future uses of
magnesium, this important reference also offers readers a glimpse
of a not-too-distant world in which environmental safety and sound
engineering are a reality.
