PROCOMAME - Processos de Conformació de Materials Metàl·lics
El grup centra la seva activitat de recerca en l’estudi dels mecanismes mecànics i físics dels materials, en particular dels aliatges metàl•lics, involucrats en els diferents processos de fabricació de components mecànics i estructurals. Es dedica un interès especial als processos basats en la deformació plàstica, en fred i en calent, com forja, extrusió, estiratge, pulvimetal•lúrgia i estampació de xapa.
L’objectiu bàsic consisteix a desenvolupar models i equacions constitutives del material que permetin la posterior simulació mitjançant càlcul numèric (FEM) dels processos. La generalització en la utilització de nous aliatges metàl•lics (acers d’ultraalta resistència, aliatges de gra ultrafí, aluminis, titanis...) dependrà de l’adaptació dels processos clàssics de conformació i del desenvolupament de nous processos. Per aquest motiu seran també objecte d’estudi altres processos de gran projecció industrial, com recobriments superficials del tipus PVD i CVD, soldadura làser, thixocasting, emmotllament per injecció, etc.
La majoria dels membres d’aquest grup tenen assignada la seva tasca de recerca al Centre Tecnològic de Manresa. Des d’aquest centre s’està duent a terme una àmplia tasca de transferència de tecnologia a empreses del sector metall-mecànic. Aquest grup de recerca es proposa transmetre els coneixements que té i genera en el seu camp mitjançant els cursos de primer i segon cicle que té encomanats, així com per mitjà del programa de doctorat del Departament de Ciència dels Materials i Enginyeria Metal•lúrgica. Així mateix, ha col•laborat i està disposat a seguir fent-ho en màsters i cursos organitzats per altres organismes, com ASCAMM i la Fundació Politècnica.
