Abstract

The influence of solute elements such as W, Re and Ru on the tensile behaviour of the gamma -phase of nickel-based model superalloys is examined. Using macroscopic tensile tests which were carried out at different temperatures as well as post mortem TEM observations, it is shown that the characteristics of the alloys are similar. However some differences are stressed and discussed in terms of differences in the nature of solute atoms. The existence and the vanishing of dislocation pile-ups as well as paired dislocations as a function of temperature is discussed.
