Interface characterization in tungsten fiber/Zr-based bulk metallic glass matrix composite

In this research, Zr55Cu30Al10Ni5 bulk metallic glass (BMG) alloy is used as the base material to form tungsten fiber reinforced BMG composites. The composites are synthetized using melt infiltration casting method and their microstructure compressive properties investigated. Two different times of 10 min 15 produce microstructural evaluation interface between matrix reveals that a narrow reaction band emerges wires alloy. Some portions layer broken into fine Zr/W-rich particles eventually dispersed in matrix, when time min. results also showed increasing from improves compression strength composite 1333 MPa 1396 increases strain 0.11 0.13. This attributed lack porosities better metallurgical bonding fibers matrix.
