Elaboration par co-déformation de matériaux stratifiés alliage léger / verre métallique

Abstract : Metallic glasses are amorphous materials displaying very interesting mechanical properties at room temperature (high fracture stresses, large elastic domain, etc.) together with an excellent formability above the glass transition temperature. However the use of these materials is limited by their lack of plasticity at room temperature. In order to extend their applications field, it could be of interest to associate metallic glasses with conventional light alloys. In this work, the feasibility of the elaboration of multilayered materials involving a Zr-based metallic glass and a magnesium alloy by co-pressing at high temperature has been investigated. The selected conditions for co-pressing were chosen from the knowledge of the rheological behavior of both the metallic glass and the light alloy. The structural characterization of the materials before and after the elaboration has been studied. The interfaces metallic glass/magnesium alloy has been characterized, revealing a good bonding between the two materials. In order to evaluate the mechanical strength of the bonding, specific tests have been developed. The results enabled us to valid the co-pressing process as a technique to elaborate multimaterials associating metallic glasses with light alloys.
