Abstract

(Cu_0.5Zr_0.425Ti_0.075)₉₉Sn₁ bulk metallic glass with a glass transition temperature of 683 K and a supercooled liquid region of 47 K was synthesized by copper mold casting. The bulk glassy alloy exhibits high strength of 1810 MPa and superior plasticity in uniaxial compression at ambient temperature. High resolution transmission electron microscopy for the bulk glassy sample subject to a plastic strain of 3% shows the formation of nanocrystallites in the glassy matrix. The plastic deformability of the (Cu_0.5Zr_0.425Ti_0.075)₉₉Sn₁ bulk metallic glass is attributed to the in situ precipitation of nanocrystallites during the compression.
