Abstract

In this paper, Zr based bulk metallic glass (BMG) composite consisting of nanocrystals embedded in the amorphous matrix was synthesized by controlled annealing treatment of a Zr41.2Ti13.8Cu12.5Ni10Be22.5 amorphous alloy. The homogeneous plastic deformation behavior of the BMG composite was characterized in the supercooled liquid region, exhibiting non-Newtonian steady state plastic flow over the investigated strain rate domain. Based upon the analysis of rheological data in terms of a modified mechanistic model, it is revealed that the mechanism of the non-Newtonian plastic flow varies with temperature, which is closely related to the presence of nanocrystals within the glassy matrix.
