Abstract

The invention discloses a Cu50Zr40Ti10 block amorphous alloy composite and a preparation process thereof. The Cu50Zr40Ti10 block amorphous alloy composite is formed by thermoforming spherical Cu50Zr40Ti10 amorphous alloy powder and a multi-walled carbon nanotube, wherein the weight ratio of the spherical Cu50Zr40Ti10 amorphous alloy powder to the multi-walled carbon nanotube is (5.91-5.997):(0.003-0.09). The carbon-nanotube-reinforced Cu50Zr40Ti10 block amorphous alloy composite has the density of 6.30-6.83 g / cm<3>, the heat conductivity of 2.15-3.32 Wm<-1>K<-1>, the compression strength of 236.8-1057.0 MPa and the strain limit of 2.1-10.0%.

Description

technical field [0001] The present invention relates to a Cu 50 Zr 40 Ti 10 Bulk amorphous alloy composite material and its preparation process. Background technique [0002] Cu-based bulk amorphous alloys are expected to become new functional and structural materials due to their excellent mechanical properties, friction and wear resistance, and corrosion resistance. However, the plastic deformation of bulk amorphous alloys at room temperature is almost zero, and its electrical and thermal conductivity are far worse than those of crystalline alloys with corresponding compositions, which greatly limits its application range. Preparation of bulk amorphous alloy composites is an important method to solve the above problems. Carbon nanotubes have extremely high strength, high electrical and thermal conductivity. If carbon nanotubes can be combined with Cu-based amorphous alloys, a bulk amorphous alloy composite with excellent electrical, thermal and mechanical properties ca...
