In a new metallic glasses near muticomponent eutectic compositions even a small composition changes have a significant effect on the T_g and T_x temperatures and therefore on the glass forming ability. In the present study the alloy of composition Ni25Cu25Zr25Ti25 (1 in at%) was melt spun amorphous. The position of the eutectic was identified as Ni29.2Cu29.9Zr17Ti24.9 (2) and the melt spun ribbon shows a better glass forming ability than the alloy (1) as manifested by DT and T_g/T_l increase. The alloy (2) was modified by manganese addition as Ti25Zr20Ni22,5Cu22,5Mn10 (3). In this alloy the eutectic was identified at Ti21Zr14Ni27Cu27Mn7 (4) and as melt spun has shown slightly better T_g/T_l.=0.63 as compared to 0.62 in the alloy (3). A second copper rich eutectic was also identified in this alloy near Ti16Zr14Ni24Cu39Mn7 (5). Nickel rich alloy of the composition Ni60Nb15Zr15Ti10 shows the eutectic composition at Ni48,5Nb21,5-Ti16.5Zr13,5 (6). The alloy (6) has been modified by silicon addition with the eutectic composition containing Ni50.3Nb14.4-Ti17.3Zr15.1Si2.8 (7). Glass forming ability was studied in NiCuZrTiAlSi alloys. The composition of the eutectic was found near Ni45.5Cu10.5Zr20Ti15-Al3.5Si5.5 (8). Present studies indicate that eutectic 4-6 component alloys lead to the increase of the T_g/T_l and DT coefficients in the melt spun amorphous ribbons.
