Abstract

We report on distinct variations in local chemistry, structure and length scale of heterogeneous regions in Ti45Cu40Ni7.5Zr5Sn2.5 fully glass rods of different diameters, i.e. rods subjected to different cooling rates. The present investigations indicate that the mechanical properties of the Ti45Cu40Ni7.5Zr5Sn2.5 bulk metallic glass can be modified within a wide range of strength and plastic deformability by controlling the scale of the heterogeneous regions in the glass through appropriate variation of the cooling rate applied for solidification.
