Of the many intermetallic compounds identified to date, only a relatively small number are candidates suitable for further development as high-temperature structural intermetallics. Were it not for the relative scarcity of ruthenium, the B2 compound

The unusual combination of high-temperature strength and room-temperature ductility makes compounds based on RuAl attractive for structural applications. Difficulties inherent in the manufacture of RuAl by melt processing can be circumvented by powde

The high thermodynamic stability and exceptional mechanical properties of intermetallic compounds based on platinum group metals (PGMs) make them potentially exploitable as structural materials for elevated temperature service. In this study, the dev

The Ru-Ni-Al system is significant for a number of reasons, not least of which is the interest in the ruthenium and nickel aluminides for high-temperature structural applications. The widely disparate properties of the B2 structured compounds NiAl an

Controlled amounts of sulphur were added to superferritic alloys based on a composition of Fe–40 wt-%Cr. The sulphur distribution was studied in relation to a series of isothermal annealing and aging cycles. The formation of a dispersion of CrS sph
