The need for enhanced turbine engine efficiency continues to drive the development of materials that can tolerate increasingly higher turbine inlet temperatures. Ordered Al-Ni-Ru B2 ternary alloys have emerged as promising materials due to the potential for Ru-modified NiAl bond coats being used in thermal barrier coating systems (TBCs) for gas turbine engines. However, to date there have not been any detailed studies of the high temperature behavior of these materials. A detailed knowledge of the high temperature mechanical and cyclic oxidation behavior of B2-based ruthenium aluminide...
