Study of the effect of Ti and Ge in the microstructure of Nb–24Ti–18Si–5Ge in situ composite
This paper made the first conclusive demonstration of the synergetic effect of Ti and Ge in improving the oxidation resistance of Nb-Si alloys, critical for strength retention in high-pressure turbine blades for next generation aero-engines. This output influenced the development of ultra-high-temperature alloys in the Vision-20 R&D in the EPSRC-Rolls-Royce research partnership (michael.hicks@rolls-royce.com) and inspired independent research on Nb-silicide alloys in National “Beyond Ni-superalloys” Programmes (DOI:10.1016/j.msea.2011.11.076, DOI:10.1016/j.msea.2012.08.027). The research led to the award of EPSRC Grant (EP/H500405/1, £504k) to develop new ultra high-temperature alloys, and an invited lecture at MS&T’12.
