About this Research Topic
The demand of eco-friendly and energy-efficient transport devices has driven the development and use of lightweight structural metallic materials (LSMM), because of their combination of properties such as high specific strength and specific modulus, better wear resistance, good corrosion resistance, etc. The use of LSMM can benefit the weight reduction of structures and therefore minimize their fuel consumption and gas emissions. There are many material systems in this category involving advanced high strength steels, Ti-, Al- and Mg-based alloys, and their composites, and this Research Topic will also cover the associated innovations in manufacturing technologies.
Achieving high strength and high ductility of LSMMs has always been a challenge, since strength and ductility are generally considered to be mutually exclusive, where increasing one will inevitably lead to a decrease of the other. However, recent studies have achieved a combination of high strength and high ductility by designing new alloys, creating novel structures, and developing innovative material processing routes. The goal of this Research Topic is to cover advanced techniques of preparing high performance LSMM and achievements in the fields of developments and applications of LSMM, and advance the current understanding on the nature of composition-process-microstructure-property interactions under simple and complex loadings.
