The Physical Metallurgy & Forming Department deals with microstructure-properties relationships, microstructure evolution and phase transformations of metal alloys. Alloy design, melting & casting considerations and the processing design (from solidification to thermo-mechanical treatment) is in focus. Scientific and engineering monitoring, development and optimization of traditional forming processes (i.e. hot and cold rolling, extrusion, drawing) including welding & joining with respect to the most appropriate material needs, is performed. Theoretical investigations, laboratory trials, planning and monitoring of industrial campaigns support these activities Following an Integrated Computational Materials Engineering approach, development of materials & processes is continuously optimized. An example of technological advancement is the development of rapid thermal processes and their effect in both microstructure and properties. An Ultra Fast Induction Processing Furnace (UFIP) has been successfully developed and installed at ELKEME S.A.’s premises.
