| Abstract Scope |
Computational design is a promising approach used in particular to predict novel compositions for new generation Ni-based single crystal superalloys. Amongst the existing approaches, some allows the exploration of new compositional fields by predicting, for eachcomposition, the ideal performances after optimization of heat treatments. Such approach does not provide, however, directions to optimize heat treatments, which remain to be determined by a classical approach. Five nickel-based single crystalline superalloys were cast with computationally designed compositions. This work was undertaken to determine heat treatments that lead to the target microstructure for the five alloys as well as improved creep strength. Once this target was reached, tensile and creep tests were carried out. In this presentation, we will more specifically detail the high temperature creep properties of theses five alloys and the tensile resistance within a wide range of conditions. |
