Abstract
The present invention discloses an aluminium-in-situ titanium boride composite powder, belonging to the field of material technology. Its composition includes (mass%) 60-99.9% of aluminium and 0.1-40% of titanium boride reinforced granules. The described powder grain size is 5-60 micrometers, and the grain size of the described titanium boride reinforced granules is 50-300 nm, and the granule form is hexagonal form or rectangular paralleling. In the powder metallurgy said invention can raise mechanical property of composite material.
Description
Technical field
What the present invention relates to is a kind of dusty material of technical field of composite materials, specifically, is a kind of aluminium-original position titanium boride composite powder.
Background technology
Aluminum matrix composite has high specific strength, high ratio modulus and high specific stiffness, has a wide range of applications in fields such as Aero-Space, national defence, industry.Powder metallurgy is one of main preparation technology of aluminum matrix composite.Usually the powder metallurgy preparation technology who adopts adds to strengthen the preparation of granules aluminum matrix composite in aluminum substrate, exists that to strengthen particle poor with the matrix wellability, and interfacial reaction is difficult to control, and the interface has influenced the performance of aluminum matrix composite in conjunction with defective such as bad.Adding aluminium-in-situ authigenic particle composite powder can well address this problem.In-situ authigenic enhancing particle and matrix wellability are good, and the interface is clean, in conjunction with good, do not have interfacial reaction layer.In powder metallurgical technique, add aluminium-original position titanium boride composite powder and can significantly improve performance of composites.
Find through literature search prior art, the Chinese patent publication number is: CN1186723, open day be: 1998.07.08, denomination of invention is: the production method of chromium carbide-nickel chromium atomized powder, this method are by atomizing preparation chromium carbide-nickel chromium atomized powder.Chromium carbide is not an in-situ authigenic in this method, problems such as technical wellability that also has the particle not have solution and a matrix and interface combination.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of aluminium-original position titanium boride composite powder material is provided, makes it can solve that to strengthen particle poor with the matrix wellability, interfacial reaction is difficult to control, the interface makes composite have higher mechanical property in conjunction with defective such as bad.
The present invention is achieved by the following technical solutions, and component that the present invention comprises and percentage by weight are: aluminium 60-99.9%, titanium boride strengthens particle 0.1～40%.
The granularity of described composite powder is 5～60 μ m.
It is hexagon or cuboid that described titanium boride strengthens grain shape.The size of particle is at 50～300nm.
Described titanium boride strengthens particle dispersion and is distributed in the composite powder, and titanium boride enhancing particle and aluminium interface are clean.
In powder metallurgical technique, aluminium-original position titanium boride composite powder and Al alloy powder are handled by mixing powder, compacting, sintering and follow-up plastic working, and the boride titanium particle disperse is distributed in the matrix.Because titanium boride is that in-situ authigenic forms, do not exist the enhancing particle to combine problems such as bad, wetability difference and interface pollution with basal body interface, composite is played good dispersion-strengthened action, the mechanical property of composite is significantly improved.The present invention adds commercial-purity aluminium in crucible, make the aluminium ingot fusing, is warming up to 850～1100 ℃; With KBF
