摘要

We report the improvement of glass-forming ability by using Nd to substitute Y in the Mg-Cu-Y bulk metallic glass (BMG). A search in the Mg-Cu-(Y, Nd) pseudo-ternary system located the best glass former at the Mg₅₇Cu₃₁Y_6.6Nd_5.4 composition, where the critical size for BMG formation (diameter D_c for copper mold casting) reached at least 14 mm. In comparison with the ternary Mg-Cu-Y glass, the Nd-containing BMG, without a significant change in Poisson's ratio, exhibits higher strength and improved compressive plasticity.
