Metal Additive Manufacturing

Additive Manufacturing is a relatively new technology to produce metallic parts in a layer by layer fashion by melting and fusing metallic powders. It is a rapid manufacturing process, where sintering, melting and solidification occur based on the heat source. The properties of the build material in powder based additive manufacturing process depend on the binding mechanism as well as the microstructure of the build material. Thus, to understand the mechanism and kinetics of consolidation of powder particles and the microstructure formation during the process may be a key factor for process optimization.

Solidification & Casting

Melt solidification is the shortest and most viable route to obtain components, starting from the design to the finished products. Hence, a sound knowledge of the solidification of metallic materials is essential for the development of advanced structural metallic components that drive modern technological societies. Solidified microstructure determines the properties of the castings, the various micro-mechanisms at different the length scales (macro-, micro-, and nano-levels). In order to obtain the desired properties of the materials at different length scale, it is necessary to close control over the processing parameters. Now days, there has been significant advances in solidification processes as well as different analytical and computer simulation techniques.
