Abstract

The invention discloses SW-CNTs fiber-reinforced magnesium alloy-based composite wire material, which is composed of the following raw material components by weight percentage: 0.5-1.5% of SW-CNTs short fibers, the balance is magnesium alloy powder, and the weight percentages of the above components The sum is 100%. The wire avoids the problem of weak interfacial bonding strength caused by poor wettability between SW‑CNTs fibers and magnesium alloy matrix, and gives full play to the comprehensive mechanical properties and physical and chemical properties of SW‑CNTs reinforced magnesium alloy matrix composites. The preparation method is as follows: step 1, high-energy ball milling; step 2, preparation of billet by semi-solid injection pressing; step 3, extrusion preparation of ultra-fine diameter wire.

Description

technical field [0001] The invention belongs to the field of metal matrix composite materials, in particular to SW-CNTs fiber-reinforced magnesium alloy-based composite material wire, and also relates to a preparation method of the SW-CNTs fiber-reinforced magnesium alloy-based composite material wire. Background technique [0002] Since the discovery of carbon nanotubes (CNTs) by Japanese scientist Sumio Iijima in 1991, new carbon nanomaterials with unique structures and excellent physical and mechanical properties have attracted extensive attention from researchers in the field of materials. CNTs are divided into multi-walled carbon nanotubes (MW-CNTs) and single-walled carbon nanotubes (SW-CNTs). High strength, elastic modulus, high toughness, excellent electrical and thermal conductivity, good structural stability and heat resistance, and at the same time it has the lightweight characteristics of carbon. Therefore, it has great application prospects in many high-tech fi...
