Abstract

Melt spun ribbons prepared from the alloys (in at.%) Zr-Ti (25-22)-Ni(24-19)-Cu(14-10) with additions of 8 and 10% Al and 10, 11 and 13% of Ag were investigated. By the addition of 10at.% Al was allowed to completely form a ribbon in the amorphous state. Modification of composition of quaternary alloy Zr-Ti25-Ni21-Cu14.5 with different Al content resulted in an increase of the glass transition, onset of crystallization and liquidus temperatures. The temperature ratio Tg/Tl decreased. Modification of the quaternary alloy composition with addition of 10-13at.% Ag and a decrease of Zr content resulted in an increased tendency for nanocrystallization. HREM observations and EDS analysis allowed us to identify nanoprecipitates as a Ag-based solid solution. This type of precipitates were observed in all Ag-containing ribbons. In comparison with the base ZrTiNiCu alloy, Ag-containing alloys possessed higher Tgand Tx temperatures and relatively high Tg/Tl value.
