Title:
METAL-BASED COMPOSITE MATERIAL, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/174159
Kind Code:
A1
Abstract:
Provided are a metal-based composite material, and a preparation method therefor and the use thereof. The metal-based composite material comprises a metal matrix and a reinforcing phase, wherein the reinforcing phase comprises a rare earth boron-carbon compound material and selected fibers which can be selectively added or not added, and the general chemical formula of the rare earth boron-carbon compound material is RExByCz, where RE is Sc, Y, a lanthanide element, etc. Medium/high-entropy RExByCz is used as a reinforcing phase of the metal-based composite material, because the RExByCz has excellent mechanical properties and high-temperature resistance, and the special layered structure thereof can effectively promote the deflection of micro-cracks so as to consume the fracture energy, such that the mechanical properties of the composite material are improved; in addition, the addition of fibers helps to improve the strength of the metal material. The finally prepared metal-based composite material can be applied in the fields of aerospace, nuclear energy, electromagnetic stealth, semiconductors, electromagnetic shielding, neutron absorption and shielding, radiation medicine, electronic device packaging, etc.
