This volume presents peer-reviewed high quality papers that reflect the research of different materials in modern building architecture, as well as their impact on the structural and strength properties of the final product. Moreover, the purpose of this volume is to present studies into the microstructural and mechanical properties of steel. Research might find useful for engineers and scientists in the field of materials science and metallurgy. Eventually, this volume's target audience includes students, postgraduates, and scientists interested in exploring thin films and composites' properties and subsequent application in various industries.
