Description
What the present invention relates to is a kind of quasicrystal particle reinforced composite, and especially a kind of Crystalloidal particles reinforced Mg-base compound material belongs to the design of matrix material and makes the class field.
Accurate crystalline substance belongs to brand-new material, is listed in the Condensed Matter Physics two big major progresses eighties with superconductor, a revolution that has not only brought conventional crystal, and the every field of Materials science produced far-reaching influence.Through the research in surplus ten years, people are structure, preparation and the performance of this material of basic understanding, and Preliminary study is to its application potential.Develop accurate brilliant non-stick pan as French scholar, recent achievement in research discloses accurate brilliant prospect as heat insulation, Chu Qing and absorption solar energy materials again.Quasicrystal material has higher hardness, low frictional coefficient, non-viscosity, good comprehensive performances such as anti-corrosion, heat-resisting, wear-resisting, and these performances and ceramic phase seemingly can be used as the matrix material wild phase.The Japan scholar accurate crystalline flour end of preparing several microns sizes, then by suitable proportion uniform mixing Al powder (＜0.2mm) and accurate crystalline flour, carry out hot pressing again, contain 25% accurate brilliant material and have optimal hardness, reach 1200Nmm
-2Accurate crystalline substance sees it is a kind of new physical form from the structure angle, but they only form in specific metal alloy in fact, it is the narrower intermetallic compound of composition range, so with metals such as aluminium, magnesium consistency and wetting property are preferably arranged, this is vital for the preparation technology who simplifies particulate reinforced composite.Through literature search to prior art, find that the people such as Suleyman B.Biner of Ministry of Energy of U.S. Iowa State University Ames Lab have declared the patent of invention of " atomizing quasicrystal particle reinforced composite and this preparation methods " (5851317 applyings date of United States Patent (USP) be: Dec.22,1998).This invention adopts the AlCuFe quasicrystal particle to strengthen aluminium and aluminium alloy, obtains particle enhanced aluminum-based composite material.Wherein, quasicrystal particle is made by atomising method, particle size 1-100 μ m.Various compression methods preparations such as this matrix material can adopt hot isostatic pressing, hot pressing, cold pressing, the volume fraction of enhanced granule is 5-70%.But the body material of this invention is only to consider aluminium and aluminium alloy, does not consider magnesium and magnesium alloy: quasicrystal particle only adopts atomising method to make, and does not consider mechanical crushing method; The solid compressed method is only adopted in the preparation of matrix material, and does not consider the liquid clotting method that stirs.
The objective of the invention is to overcome deficiency of the prior art, the scope that has particularly enlarged the design of quasicrystal particle reinforced composite and made has proposed a kind of Crystalloidal particles reinforced Mg-base compound material.
Technical scheme of the present invention and summary of the invention are as follows:
The present invention selects for use the AlCuFe quasicrystal particle as the magnesium alloy substrate strongthener, and AlCuFe is accurate brilliant except that the premium properties with quasicrystal material, and its composition is three kinds of the most frequently used metals simultaneously, and raw material sources are abundant; AlCuFe is accurate brilliant stable on thermodynamics, belongs to stable accurate brilliant, can prepare with any conventional alloy preparation method, as long as the fusing composition is alloy material accurately, cast molding is carried out suitable thermal treatment again and is got final product, so the accurate brilliant preparation of AlCuFe also is very easily.Body material of the present invention becomes component selections as follows: Mg
