L’entreprise sidérurgique sarroise AG der Dillinger Hüttenwerke (Dillinger) entend perpétuer sur le long terme son partenariat stratégique aves les facultés des Sciences et du Génie des matériaux de l’Université de la Sarre et le centre de recherche Steinbeis MECS (Centre d’ingénierie des matériaux de la Sarre). Depuis 2014, le spécialiste de l’acier a déjà soutenu des projets de recherche communs consacrés à l’acier pour un montant de près d’un million d’euros. Grâce à ces aides, trois professeurs de l’Université de la Sarre et leurs équipes ont pu travailler sur ce matériau aux multiples facettes.
