Abstract

The invention discloses a nano-particle reinforced copper-based composite material and a preparation method thereof. The size of a copper matrix grain is smaller than 20 microns in the copper-based composite material; the nano-particle reinforced phase is molybdenum carbide, or molybdenum carbide and molybdenum, or molybdenum carbide and carbon; the particle size of the nano-particle reinforced phase is smaller than 200nm; the mass percent of Mo in the copper-based composite material is 0.1-15%; the mass percent of C is smaller than 1%. The nano-particle reinforced copper-based composite material disclosed by the invention is prepared by adopting an electronic beam physical vapor deposition process. The nano-particle reinforced copper-molybdenum-carbon composite material prepared by the method has excellent mechanical property and electrical property, and adopted electronic beam physical vapor deposition process is simple, low in cost and easy to control.

Description

technical field [0001] The invention relates to a copper-based composite material reinforced by nanoparticles and a preparation method thereof, in particular to a copper-molybdenum-carbon composite material reinforced by nanoparticles and a preparation method thereof. Background technique [0002] Copper and copper alloy materials are important non-ferrous metal materials, which have been widely used in the electronics industry and other fields due to their excellent physical and mechanical properties. However, with the rapid development of science and technology (especially the rapid development of the microelectronics industry), traditional copper and its alloys cannot meet the requirements due to the inability to balance electrical properties and strength. Nano-dispersion-strengthened copper alloy is a new type of composite material with nanoparticles as the second phase. Because nanoparticles can effectively hinder dislocation movement and grain boundary slip, the mechan...
