Abstract

A method of static quenching has been put forward to prepare the Zr-based bulk metallic glass (BMG) in this work. Compared with the traditional method of copper mold suction casting, the compressive plasticity of Zr₆₀Ni₂₅Al₁₅ BMG can be improved from nearly 0 to 6.5% through the method of static quenching. An underlying reason of the improved plasticity has been clarified as that the cooling rate of static quenching is larger than that of copper mold suction casting, and there are more soft spots in the static quenching sample than suction casting. The corresponding mechanism has also been discussed.
