3Preparation of Al-Cu-Fe-(Sn,Si) quasicrystalline bulks by laser multilayer cladding显示文摘(Al65Cu20Fe15) 100-x Sn x(x=0,12,20,30) and Al57Si10Cu18Fe15 powders were cladded on a medium carbon steel(45# steel) substrate by laser multilayer cladding,respectively.The phases and properties of the produced quasicrystalline bulks were investigated.It was found that the main phases in the Al 65 Cu 20 Fe 15 sample were crystalline λ-Al13 Fe4 and icosahedral quasicrystal together with a small volume fraction of θ-Al 2 Cu phase.The volume fraction of icosahedral phase decreased as the Sn content in the(Al65Cu20Fe15) 100-x Sn x samples increased owing to the formation of β-CuSn phase.The increase of Sn content improved the brittleness of the quasicrystal samples.The morphology of the solidification microstructure in the Al57Si10Cu18Fe15 sample changed from elongated shape to spherical shape due to the addition of Si.The nanohardness of the laser multilayer cladded quasicrystal samples was equal to that of the as-cast sample prepared by vacuum quenching.In terms of hardness,the laser cladded Al57Si10Cu18Fe15 quasicrystalline alloy has the highest value among all the investigated samples.Li-ping Feng Eric Fleury Guo-sheng Zhang 2012International Journal of Minerals,Metallurgy and Materials2012,19,5:0
4Elaboration of AlSi10Mg casting alloys using directional solidification processing显示文摘The effects of pulling velocity on the solidification behavior and microstructural parameters of Al Si10 Mg alloys prepared in a Bridgman-type directional solidification furnace were investigated. The microstructure, particularly the secondary dendritic arm spacing(SDAS), and the Brinell hardness(BH) of the solidified Al Si10 Mg alloys were characterized for samples with cylindrical shapes and different conicities(θ = 0°, 5°, and 10°). Microstructural studies revealed an increased density of α–Al phase dendrites and a decreased interdendritic distance with increasing pulling velocity. The dendrites were found to be preferentially oriented along the pulling direction for low pulling velocities. For larger pulling velocities, the dendrites grew first in the cooling direction but then broke as others nucleated and coarsened. The HB values of the solidified samples increased as the pulling velocity increased. In regard to sample conicity, smaller dendrites were observed for an apex angle of θ = 5°, resulting in the largest HB value. This result was interpreted in terms of the favorable orientation of the dendrite along the pulling direction.Khadoudja Ghedjati Eric Fleury Mohamed Seghir Hamani Mostefa Benchiheub Khaider Bouacha Bernard Bolle 2015International Journal of Minerals,Metallurgy and Materials2015,22,5:0
