Tóm tắt

Biocompatible TiZr-based bulk metallic glass foam (BMGF) plays a critical role for bio-implant application. In this present work, a series of TiZr-based BMGFs were successfully fabricated by using hot pressing method in an inert gas chamber. Amorphous structure and high compactivity of the TiZr-based BMGF were required to retain excellent properties. Temperature and holding time during hot pressing process significantly impact on fabrication of the TiZr based BMGF. Results from differential scanning calorimetry (DSC) and XRD analysis point out that the applied temperatures from 763 to 793K with holding time from 3 to 5 min are suitable for producing the TiZr-based BMGF. As a result, the bulk alloy foam produced at the temperature of 793K and holding time of 5 min still remain amorphous state and display a high-density compact structure after hot pressing. Bright-field TEM image indicates that the TiZr-based BMGFs present a strong bonding-force interface between amorphous metallic glass particles which can make a good condition for generating the foam with higher porosity in further study.
