【摘要】 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(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%。更多还原

【Abstract】 Mechanical properties of(Zr41.2Ti13.8Cu12.5Ni10Be22.5)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.更多还原
