The 2019 International Conference on Metals and Alloys (CMA 2019) will be held from August 19 to 22 in Beijing, China. The overall objective of the conference is to bring together international scientists and engineers in academia and industry in fields related to research in metals and alloys, more specifically related to their mechanical behaviour, material properties, metallurgical behaviour and microstructures etc., and their applications to a wide range of engineering disciplines. All types of metals, e.g. iron, brass, copper, aluminium, steel, etc., and all types of alloys, e.g. stainless steel, alloys of gold and silver, high temperature alloys, magnetic alloys, etc., are considered in CMA conference. The conference covers industrial engineering applications of metals and alloys to Civil Engineering, Aerospace Engineering, Materials Engineering, Mechanical Engineering, and Biomedical Engineering, etc.
