| Abstract Scope |
Titanium superalloys are important materials for high performance applications due to their outstanding tensile strength, high resistance to creep deformation and corrosion. Optimizing their strength, hardness, and cost is important for the industries that rely on these alloys. Within these boundary conditions, an application specific composition selection could be made possible if a detailed catalog of material and mechanical properties existed for different compositions in the Ti-Al-Nb and Ti-Ni-Nb system. In this research, results are presented from a high-throughput study on two such ternary superalloy systems, Ti-Al-Nb and Ti-Ni-Nb, where Ti, Nb, and Al/Ni were sputtered into a thin film using a combinatorial magnetron sputtering method on sapphire or silicon substrates. Energy dispersive x-ray spectroscopy is used for local compositional analysis while x-ray diffraction is used for phase analysis. Finally, nanoindentation is used to correlate the effective modulus and hardness of different alloy compositions in the alloy systems. |
