Preface
We would like to present the book Light Weight Materials: Processing and Characterization. In the automotive industry, the need to reduce vehicle weight has led to extensive research efforts to develop aluminum and magnesium alloys for structural car body parts. In aerospace, the move towards composite airframe structures has led to an increased use of formable titanium alloys. All of the above-mentioned materials can be categorized into a group called “lightweight materials”. The distinguishing feature of lightweight materials is their low densities, ranging from as low as 0.80 g/cm3 for unfilled polymers to as high as 4.5 g/cm3 for titanium. Although the density of titanium is higher than that of unfilled polymers, it is significantly lighter than metals: alloy steel (7.86 g/cm3) and superalloys (7.8–9.4 g/cm3). In a nutshell, lightweight materials exhibit a wide range of properties and therefore offer a wide range of applications.
