Abstract
The compositions of Zr41Ti14Cu12Ni10Be23 and Zr55Ni10Cu20Al15 bulk metallic glasses (BMGs) were modified by the addition of other elements, such as Nb, Fe, Mg, Y, Ta, and C. The modified alloys exhibit excellent glass forming ability (GFA). The glass transition temperature T g, crystallisation temperature T x, and offset melting temperature T l of the composition modified Zr based alloys were determined by differential temperature analysis (DTA).Results show thatthe T g, T x,and T lare allsensitive to the composition. The undercooled temperature from T l to T x, Δ T l defined by Δ T l = T l - T x, has a stronger correlation with the reduced glass transition temperature T rg (T rg = T g/ T l) than Δ T x (Δ T x = T x - T g).
