This volume is a compilation of papers that were presented at Symposium 4A: 'Advanced Structural Materials' of the XXII International Materials Research Congress, organized in collaboration with MRS, which was held from August 11 to 15, 2013 in Cancún, Mexico. The symposium was devoted to fundamental and technological applications of structural materials, and continued the tradition of providing a forum for scientists from various backgrounds with a common interest in the development and use of structural materials to come together and share their findings and expertise. The 'Advanced Structural Materials' symposium has been held for the last nineteen years with the objective of presenting overviews and recent investigations related to advanced structural metallic, ceramic and composite materials. The topics include innovative processing, phase transformations, mechanical properties, oxidation resistance, modeling and the relationship between processing, microstructure and mechanical behavior. Additionally, papers on industrial application and concrete are included.
