ULTMAT project (January 2004 for 48 months), aims at providing sound technological basis for the introduction of Mo- and Nb-base silicide multiphase alloys, with enhanced high temperature capabilities (up to 1300°C) for applications in aero-engine turbines. The development status of new alloys is presented, focusing on creep and oxidation properties.
