Two indispensable factors that form an industrially advanced society are Materials and Energy. Transformation and flow of energy and materials within a system determines quality of the modern life. For production, and utilization of energy at every stage, often materials with special properties are required. The properties of materials, on the other hand, is originated from the internal structure and arrangement of atoms. Therefore, progress in understanding of properties-structure of materials is essential for developing new materials to improve efficiency of energy applications and thus the quality of life in the society. Most of the materials must be assembled into structures and their performances also rely on the welding & joining technologies used for their assembly.
Our research activities include development of advanced materials, processes, and manufacturing techniques.
Advanced Electronic Materials
Advanced Electronic Materials
Traditionally, Sn-Pb alloy has been the major alloy for electronics manufacturing and SMT (surface-mount technology) assembly due to its superior performance, high reliability and low cast. However, the inherent toxicity of lead with associated environmental and public health concerns have pushed the electronic industries towards lead-free materials. The environmental and regulatory requirements ,WEEE & RoHS, are two main factors forcing conversion even in exempt industries such as Aerospace, Automotive and Medical, due to the supply chain dynamics.
Joining & Welding
Joining & Welding
“Joining is an inevitable part of every engineering and manufacturing sector. A welded joint covers the entire field of metallurgy and all states of matter”.
In most applications, various materials need to be joined either to each other or to other structural or functional materials. Achieving high quality joints is the key in various fields such as energy conversion systems, aerospace, automotive, process industries, electronic, and medical systems. Welding, soldering, brazing are key enabling technologies in introducing these systems into industrial use.
Materials Processing
Materials Processing
Materials Processing such as deformation, heat treatment, and thermo-mechanical processes play important role in the design and engineering of structure and mechanical properties of materials. For example, by the deformation speed and temperature the phase change (displacive or reconstructive) and ultimate microstructure of an steel product can be engineered and controlled.
