An unusual combination of high melting point (2050[degrees]C, 3720[degrees]F), thermodynamic stability, toughness, corrosion resistance, thermal and electrical transport properties, oxidation resistance, and amenability to substitutional alloying has led to development efforts of ruthenium aluminides by Mintek, South Africa.
One of the development paths followed for the production of RuAl starts with the two-phase mixture that can be equilibrated between the B2 RuAl and the Ru (hcp)-RuAl eutectic. In melt-processed material, ruthenium-rich stoichiometries result in the formation of an inter...
