采用XRD、SEM等表征方法研究钨丝增强(Zr41.2Ti13.8Cu12.5Ni10Be22.5)100-xNbx非晶复合材料的力学行为.研究表明,分别加入x=1,3,5,7(atA)的Nb后,制备的复合材料试样基体仍为非晶态:随Nb含量的增加,钨丝增强(Zr41.2Ti13.8Cu12.5Ni10Be22.5)100-xNbx非晶复合材料的压缩屈服强度提高,塑性应变也随之提高.x=7时,复合材料具有良好的综合性能,压缩屈服强度达2450 MPa,塑性应变达20%.

Mechanical properties of(Zr41.2Ti13.5Cu12.5Ni10Be22.5)100-xNbx bulk metallic glass(BMG)matrix composites reinforced by tungsten fiber(Wf)were investigated by X-ray diffraction, scanning electron microscope(SEM)and so on. The results show that the matrix of the prepared composites remain amorphous after adding Nb with x=1, 3, 5 and 7, at%, and the compressive yield strength and plastic strain increase with the increase of Nb content. The composites with x=7 possess the excellent comprehensive properties, whose compressive yield strength and plastic strain reach 2450 MPa and 20%, respectively.
