| Abstract: | Fe-based bulk glassy alloys were consolidated using spark plasma sintering(SPS) process with amorphous powers prepared by inert gas atomizing method as raw material.The effects of sintering parameters such as temperature,pressure,holding time et al.on the phase,density,microstructure and properties of the sintered bodies were investigated.It is found that dense bulk metallic glass alloys with enhanced properties could be obtained by SPS when the sintering parameters are suitable. |
