1 Aubert & Duval

AUBERT & DUVAL undertook 25 years ago the realization of the first cast tools dedicated to superplastic forming. The experience feedback among our customers and the evolution of technology led us to adapt our offer of alloys intended for the tools, by optimization of existing nuances or the development of specific grades. The programs of studies realized with the French Group of Superplasticity and the collaborations established with Research Centers such as the “Ecole des Mines d'Albi (CROMeP)” or the “University of Nottingham” enabled us to undertake these developments on reliable bases in connection with the industrial conditions of operating. In parallel these collaborations made it possible to make evolve the foundry design of the tools and to approach the aspect of maintenance and repair of tools. This paper will try to make the synthesis of this experiment.
