Investigation on dynamic mechanical properties of tungsten fiber reinforced metallic glass composite

摘要

Recently developed bulk metallic glass (BMG) alloys have attractive mechanical properties for structural applications, and tungsten fiber reinforced bulk metallic glass matrix composite (BMGC) would further improve the properties compared to un-reinforced BMG. With INSTRON1196 test machine system and SHPB experimental system, quasi-static and dynamic compression experiments on tungsten fiber reinforced bulk metallic glass matrix composite were carried out. The material flow stress is about 2200MPa in quasi-static, and the dynamic flow stress of the material is around 2800MPa with strain rate of 740 s~(-1). The specimen fails with the form of axial cracks.
