| Abstract | Bulk metallic glasses (BMGs) are synthesized using high energy mechanical ball milling technique with the general formula, [Ni-Cr-Si]100-x:Nbx(x = 0, 3, 6 and 9 at.%, labelled as NCSNb0, NCSNb3, NCSNb6, NCSNb9). Interestingly, all the thermal, mechanical and corrosion properties aregreatly enhanced with increase in Niobium(Nb) content upto 6 at.% (NCSNb6). XRD analysisshows that the phase attribution over all the BMGs is due to Nickel(Ni, 98-006-0833), Chromium(Cr, 98-002-1500), Silicon(Si, 98-001-2990) and Niobium(Nb, 98-002-3331). The values of the largest super-cooled liquid region width and plastic strain attained are 232 K and 0.94?0.1%, for the NCSNb6BMG sample. The considerable addition of Niobium(Nb ?6 at.%) content in [Ni-Cr-Si] BMG network (NCSNb6) is anticipated to havethe best glass-forming ability, mechanical and corrosive resistant properties and is expected to be used as potential material for lightweight vehicle applications |
