PROCESSES: ISF 2G
Excellence of Spain in Rapid Manufacturing. Development and application of the second-generation technology of incremental deformation for strategic applications.
ISF 2G is a consortium project financed by the Ministerio de Industria, Turismo y Comercio (Ministry of Industry, Tourism and Commerce). The project focuses on incremental deformation of metallic sheets as a rapid manufacturing technology for components for sectors characterised by manufacturing short series (aerospace, capital goods, special vehicles, etc). The different collaborating centres contribute their knowledge and expertise in different areas of science and technology. CTM, as a company subcontracted by FATRONIK, carries out the characterisation of the hot behaviour of Ni based super-alloys. To be specific, the project seeks to define safe working advantages so as to prevent the appearance of mechanisms which might increase the fragility or excessively increase the stresses that might take place as a result of the precipitation, which is a phenomenon that occurs in these materials. So as to achieve this objective it is necessary to know the mechanical behaviour of these materials, the recrystallisation kinetics and the statics and dynamics, as well as the kinetics of phase precipitations such as ?, ?' or ?''. Likewise, it is important to determine the effect of deformation on this kinetics since under deformation conditions the appearance of these phases can be accelerated and it might even interfere with the forming processes. Given the nature of these phenomena the evaluation of hot ductility will make it possible to know under which working conditions these could lead to cracking.
Companies and centres which are collaborating on the Project apart from CTM: Fundació Ascamm (ASCAMM), Centro Láser of the Universidad Politécnica de Madrid (CLUPM), Centro Tecnológico del Metal de Murcia (CTMM), Fundación Fatronik (FATRONIK) and the Instituto Tecnológico de Castilla and León (ITCL), UPC.
