The effect of interphase elemental partitioning on the lattice misfit of high cobalt and titanium containing superalloys

Abstract: New superalloys with higher temperature capability are required for more efficient gas turbine engines in civil aviation. Recent research has identified that alloys with elevated co-additions of cobalt and titanium offer improved properties over conventional nickel-based superalloys. However, a greater understanding of the phase equilibria and crystallography of such alloys is required before commercial alloys of this type may be realised. In this experiment, diffraction data will be acquired from 7 quinary Ni-Co-Al-Ti-Cr alloys to study systematically the effect of temperature on the lattice parameters of the two main constituent phases and their associated lattice misfit. These data will provide insight into the relative contribution of coherency strengthening to the overall mechanical properties in such alloys, which will aid future alloy design.
