IMPROVEMENT OF PLASTICITY OF TI-BASED BULK METALLIC GLASSES BY PHASE TRANSITION OF A COOLING MEDIUM

摘要：

Ti-based bulk metallic glasses (BMGs), Ti40Zr25Cu9Ni8Be18, were prepared by phase transition cooling (PTC) and copper mould casting(CMC) technology. Ti40Zr25Cu9Ni8Be18 glassy rod of more than 13 mm in diameter was prepared by PTC technology which shows the high cooling rate obtained by this technology. No obviously differences in thermal property were found between the BMGs prepared by the PTC and CMC technology. The compressive plasticity of the alloy was apparently changed, from 8％ using CMC to 37％ by using PTC technology. PTC technology is probably a promising method for preparing BMG and an effective way to increase the plasticity of BMGs.
