The
interaction of aluminum with niobium and scandium in equilibrium and
nonequilibrium states
Abstract
By using of the complex methods of the physico – chemical analysis it
was found that only phases based on binary intermetallic compounds ScAl3
and NbAl3, containing a small amounts of the dopants are in
equilibrium with aluminum in the Al–Nb–Sc system. Aluminum and binary phases
ScAl3 and NbAl3 come into eutectic equilibrium at 873±5
K. The joint dopping of aluminum by niobium and scandium reduces the extent of
the area of the supersaturated solid solution based on aluminum.
Key words: Al–Nb–Sc
alloys, rapidly quenched alloys, isothermal section of the ternaru system,
polythermal section.
