【摘要】 针对具有多相复合结构的[(Zr_0.5Cu_0.5)_99.5-xAl_xSn_0.5]_0.97Ta₃（摩尔比）非晶复合材料，通过调控Al含量（x=5,6,8），探讨了非晶复合材料微观组织及力学性能的变化规律。研究表明，Al含量会对复合体系中基体的非晶形成能力产生影响。随着Al含量的增大，体系中的非晶形成能力先增大后减小。非晶形成能力的变化会对凝固过程中析出的多相增强结构含量及尺寸产生相应影响，进而影响非晶复合材料的屈服强度和塑性变形能力。因此，可根据不同性能需求进行成分选择，实现合金组织与性能的可调可控。更多还原

【Abstract】 The microstructure and mechanical properties of [(Zr_0.5Cu_0.5)_99.5-xAl_xSn_0.5]_0.97Ta₃（molar ratio） amorphous alloy matrix composites with multiple reinforcing phases were investigated by adjusting Al content（x=5,6,8）. The results indicate that Al content affects the glass formation ability of matrix. With the increase of Al content, the glass formation ability of system is increased firstly and then decreased. The variation of glass formation ability has a corresponding effect on content and dimension of the multi-phase reinforcing structure during solidification, thus affecting the yield strength and plastic deformation of amorphous composites. Therefore, the composition can be selected according to different performance requirements to achieve the adjustability and controllability of microstructure and properties.更多还原
