Abstract

TiCuNiCo quaternary amorphous alloys produced by melt spinning were found to have a wide supercooled liquid region before crystallization, though no glass transition was observed in TiCu binary amorphous alloys. The largest temperature interval of the supercooled liquid region (ΔTx) is as large as 90 K for Ti50Cu25Ni20Co5. There is a tendency for ΔTx to increase with an increase in storage modulus and with a decrease in loss modulus. It is therefore presumed that the increase in ΔTx for the multicomponent amorphous alloy is due to the suppression of crystallization for the supercooled liquid resulting from the increase in viscosity.
