Description
The utility model relates to composite material, the particle reinforced aluminum alloy base functionally graded composite tube that specifically a kind of internal and external layer is strengthened simultaneously.
FGM be by a Japanese scientist Xinye just at " material foundation " 1987, the volume 10, the page or leaf 31 (M.Niino:Funct.Mater., 1987, vol.10, p.31) the middle a kind of advanced composite material (ACM) that proposes, SiC or the Al for preparing about centrifugal cast iron pipe at present
2O
3Equidensity is greater than the particle reinforced aluminum alloy base functionally graded composite tube of aluminum matrix alloy, and according to the refined history of Hooke, the learned history of watt is at " metallurgy and material transactions A ", 1996, volume 27A, page or leaf 4145 (Y.Fukui, and Y.Watanabe:Metall.Mater.Trans A., 1996, vol.27A, p4145) and Liu Qingmin, Jiao Yuning, Yang Yuansheng, Hu Zhuanqi is at " metallurgy and material transactions B ", and 1996, volume 27B, page or leaf 1025 (Q.M.Liu, Y.N.Jiao, Y.S.Yang, and Z.Q.Hu:Metall.Mater.Trans B., 1996, vol.27B, p1025) report, the percentage by volume of particle reduces gradually from outer surface to the internal surface of composite pipe in the composite pipe, it is limited that it strengthens the position, has only skin.
The purpose of this utility model provides and a kind ofly satisfies inner and outer surface and strengthen simultaneously, and the mesosphere has the particle reinforced aluminum alloy base functionally graded composite tube of excellent toughness.
The technical solution of the utility model is: by the gradient-structure that particle enriched layer and particle meager set layer are formed, wherein: described particle meager set layer is distributed in the mesosphere, and the particle enriched layer is distributed in internal layer and skin.
The utlity model has following advantage:
1. mechanical property is good.The utility model utilizes non-vacuum induction furnace and horizontal centrifugal casting machine, makes particle (SiC, the Al of density greater than aluminum matrix alloy (cast aluminium alloy or wrought aluminium alloy)
