Formation and characterization of an Al-rich metastable phase in the Al–B phase diagram
Vacuum heat treatment of mechanically alloyed powders of boron and aluminium leads to the formation of a metastable Al-rich phase, which can be quenched. Its structure, composition and thermal stability are established. With the chemical formula Al 1.28 B the rhombohedral phase is unusually rich in Al. The parameters of …
