The book "Advanced Light Alloys and Composites" offers a comprehensive analysis of the structural and mechanical properties of light alloys and composites. It is aimed at scientists and engineers and highlights advanced materials, their structure, properties, technologies, and applications. The focus is on aluminum alloys, with detailed coverage of their properties, casting technologies, thermomechanical treatments, and structures. Additionally, magnesium alloys, particularly those with rare earth elements, as well as commercial titanium alloys and intermetallic compounds are discussed. The book also addresses metallic composites and the latest engineering techniques from both theoretical and practical perspectives.
