%X Elements Si and B in the Ti50Ni22Cu18Al4Si4B2 alloy are substituted with Sn to form the Ti50Ni22Cu18Al4Snx(Si0.67B0.33)6-x(x=0, 3, 6) series alloys. In all cases, mechanical milling of the prealloyed fragments results in the amorphization of the alloys. With increasing the Sn content in the alloys, the fraction of residual a-Ti crystallites in the final milled product was reduced. For the Ti50Ni22Cu18Al4Sn6 alloy, in which the Si and B are completely replaced with Sn, the nearly complete amorphization is achievable. A single amorphous phase, similar to the melt-quenched glass, formed in the milled alloy. Such a, ball-milled glassy alloy exhibits a large supercooled liquid region about 66 K.
