Summary on Grant Application Form |
|
The aim of this research programme is to assess a way of increasing the operating tremperature of aero and land-based turbine engines. It is planned to replace Ni single crystal blades with Nb silicides which have optimised high temperature properties. The inevitable lack of room temperature ductility in these materials will be overcome by investigating the feasibility of diffusion bonding a high Si-content Nb silicide (which will have good high temperature properties appropriate to a blade) to a high Nb-content Nb silicide which will have signficant ductility (appropriate for a blade root) but reduced high temperature strength. Powder-route material will be used so that consolidation and diffusion bonding will be carried out simultaneously which should allow good bonding and shape control during HIPping. A preliminary assessment will be made of the feasibility of using nanopowders in this work. Oxidation studies of the chosen compositions will be carried out.
