Acta Metallurgica Sinica (English Letters) provides an international medium for the publication of theoretical and experimental studies related to the fields of metallurgy, materials science and engineering. The studies which advance the understanding of the relationship between the structure and the properties or the functions of inorganic materials are of particular interest. Coverage extends to the fields of metals and related nano-materials, biomaterials, energy materials, environmental materials, crystal materials, ceramic materials, composites, thin film and coating, oxidation and corrosion, etc. *Advance the understanding of the relationship between the structure and the properties or the functions of inorganic materials. *Mainly cover metals and related nano-materials, biomaterials, energy materials, environmental materials, crystal materials, ceramic materials, composites, thin film and coating, oxidation and corrosion, etc. *Article type including Review, Research article, Letter, Rapid communication, etc. .
