Mechanical properties of tungsten fiber reinforced (Zr41.2Ti13.8Cu12.5Ni10Be22.5)100-xNbx metallic glass matrix composites
采用XRD、SEM等表征方法研究了钨丝增强(Zr41.2Ti13.8Cu12.5Ni10Be22.5)100-xNbx非晶复合材料的力学行为。XRD表明，分别加入x=1、3、5、7 (at.%)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2450MPa，塑性应变达20%。
Mechanical properties of tungsten fiber reinforced (Zr41.2Ti13.8Cu12.5Ni10Be22.5)100-xNbx amorphous alloy matrix composites were investigated by X-ray diffraction, SEM and so on. The results showed that after adding x=1, 3, 5, 7 (at.%) Nb, the matrix of the prepared composites remained amorphous, compressive yield strength and plastic strain increased with the content of adding Nb. The composites with x=7 had the excellent comprehensive properties, the compressive yield strength and plastic strain reached 2450Mpa and 20%, respectively.
