Abstract

The invention relates to a preparation method of a magnesium-zinc-yttrium quasicrystal and titanium carbide synergistically strengthened magnesium-based composite materials. Aiming at the poor mechanical properties of magnesium-based composite materials, the magnesium-zinc-yttrium quasicrystal and inner Synergistically strengthened magnesium-zinc-yttrium-zirconium alloys with raw titanium carbide, and made magnesium-zinc-yttrium quasicrystals and titanium carbide synergistically strengthened magnesium matrix composites through smelting, argon bottom blowing, mechanical stirring, electromagnetic stirring and extrusion casting; this preparation The method has advanced technology, strict procedures, and accurate and detailed data. The tensile strength of the prepared magnesium-based composite material reaches 268MPa, the hardness reaches 93.5Hv, and the elongation rate reaches 8.1%. It is an advanced synergistic strengthening of magnesium-zinc-yttrium quasicrystal and titanium carbide. Preparation method of magnesium-based composite material.

Description

technical field [0001] The invention relates to a preparation method of a magnesium-zinc-yttrium quasi-crystal and titanium carbide synergistically strengthened magnesium-based composite material, which belongs to the technical field of non-ferrous metal composite material preparation. Background technique [0002] Magnesium alloy is known as the green engineering material of the 21st century, which has the advantages of light weight, high shock absorption performance, good casting performance, good cutting performance, good anti-electromagnetic interference and shielding performance. These characteristics make magnesium alloys widely used in aerospace, rail transit, biomedicine, electronic products, architectural decoration and national defense. However, magnesium alloys have the disadvantages of poor wear resistance, low tensile strength and low hardness. With the development of modern industry, it is difficult for a single magnesium alloy to meet the requirements of actu...
