Heat-Resistant RuAl-Based Alloys: III. Powder Alloys—Mechanical Alloying

Inorganic Materials: Applied Research, 2021
Refractory (Tmelt = 2100 °C), heat-resistant ruthenium monoaluminide RuAl, lighter (ρ = 7.97 g/cm3) than Ni superalloys, is considered as a promising candidate material for operation at high temperatures and relatively low loads in high-speed gas oxidizing flows at temperatures higher not only operating temperatures, but also the melting temperatures ...

Casting alloys

Dental Clinics of North America, 2004
Although the role of dental casting alloys has changed in recent years with the development of improved all-ceramic materials and resin-based composites, alloys will likely continue to be critical assets in the treatment of missing and severely damaged teeth. Alloy shave physical, chemical, and biologic properties that exceed other classes of materials.

Scandium-alloyed aluminum alloys

Metal Science and Heat Treatment, 1992
The basic principles of alloying of aluminum alloys with scandium are: it is desirable to add scandium to aluminum alloys in a quantity from 0.1 to 0.3% together with zirconium (0.05–0.15%), which strengthens the positive influence of scandium on the structure and properties of alloys; the greatest effect (that is, the positive influence on mechanical ...

Calcium-alloyed magnesium alloys

Metal Science and Heat Treatment, 2009
Mg - Al - Ca alloys positioned in the Mg - Al 2 Ca quasi-binary section are studied. It is shown that alloys of this system bearing the Al 2 Ca compound as a hardening phase can be used for developing structural alloys with elevated strength at 170°C and that the strength characteristics of the Mg - Al - Ca alloys can be improved by adding manganese.
