ABSTRACTAmorphous structures or metastable crystalline phases are produced in sputter deposited Be-Nb alloys (5–15 at.% Nb) depending on the substrate temperature. The metastable phases transform to the stable Be12Nb, Be17Nb2 or Be3Nb phases on annealing at temperatures >800°C. No Be5Nb phase was found and the Be17Nb2 phase is stable to low temperature. The Be12Nb phase appeared to have a stoichiometric range of about 5.5 to 7.7 at.% Nb. The formation of the metastable phases is consistent with current models and theories.

ABSTRACTRapid quenching of binary Ti alloys from the melt results in various metastable phases. A systematic study has been conducted in order to elucidate principles associated with the formation of metastable phases in binary Ti alloys resulting from rapid quenching. These metastable phases that include α’, α” phases, metastable β phase, and w phase are discussed with regard to their occurrence and the extension of a phase as a function of cooling rate. Effect of cooling rate and mechanical stress applied during cooling on metastable phase formation was investigated.
