L'alliage ainsi défini présente une faible densité, un faible coefficient de dilatation et de bonnes caractéristiques mécaniques. Il trouve des applications dans les pièces chaudes et en mouvement des moteurs automobiles telle que pistons, chemises, bielles, axes de pistons, insert de culasse etc...The alloy thus defined has a low density, a low coefficient of expansion and good mechanical characteristics. It finds applications in hot and moving parts of automobile engines such as pistons, liners, connecting rods, piston pins, cylinder head insert, etc.
On sait que l'eutectique de l'alliage Al - Si se situe aux environs de 12 % de silicium et que le surplus de silicium cristallise en général pendant la solidification et le refroidissement, sous forme de cristaux de silicium très durs qui sont d'autant plus gros que la vitesse de refroidissement est plus faible.It is known that the eutectic of the Al - Si alloy is around 12% of silicon and that the surplus of silicon generally crystallizes during solidification and cooling, in the form of very hard silicon crystals which are of the larger the lower the cooling rate.
Les cristaux de silicium quand ils sont trop gros présentent des inconvénients évidents pour l'usinabilité, l'homogénéité et les caractéristiques mécaniques des pièces.Silicon crystals when they are too large have obvious drawbacks for the machinability, the homogeneity and the mechanical characteristics of the parts.
Le procédé qui fait l'objet de l'invention permet de réaliser des pièces en alliage d'aluminium hypersilicié comportant des cristaux de silicium de taille inférieure à 1 µ soit 1 millième de millimètre ou du silicium à l'état de solution solide.The process which is the subject of the invention makes it possible to produce parts in hypersilicon aluminum alloy comprising silicon crystals of size less than 1 μ, ie 1 thousandth of a millimeter or silicon in the state of solid solution.
On connait des procédés de fabrication de pièces en alliage d'aluminium hypersilicié utilisant les techniques de la métallurgie des poudres. Ces techniques consistent à transformer les lingots d'alliage en poudre par centrifugation et atomisation. Les grains de poudre dont les dimensions sont de l'ordre de 500 µ refroidissent plus vite que les lingots de telle sorte que les cristaux de silicium ont des dimensions allant de 5 à 25 µ . Lorsque les poudres sont forgées ou filées à chaud les grains grossissent dans un rapport 2 et atteignent 10 à 50 µ .Processes are known for manufacturing hypersilicon aluminum alloy parts using the techniques of powder metallurgy. These techniques consist of transforming the alloy ingots into powder by centrifugation and atomization. The grains of powder whose dimensions are of the order of 500 μ cool more quickly than the ingots so that the silicon crystals have dimensions ranging from 5 to 25 μ. When the powders are forged or hot spun, the grains grow in a ratio 2 and reach 10 to 50 µ.
Le procédé qui fait l'objet de l'invention définit d'une part des moyens pour obtenir une poudre dont les dimensions des grains varient de 0 à 120 µ avec des cristaux de silicium inférieurs à 1 µ ou de silicium en solution solide ; et d'autre part des moyens pour extruder des pièces à partir de cette poudre sans grossir les cristaux de silicium.The process which is the subject of the invention defines, on the one hand, means for obtaining a powder whose grain dimensions vary from 0 to 120 μ with silicon crystals of less than 1 μ or of silicon in solid solution; and on the other hand, means for extruding parts from this powder without enlarging the silicon crystals.
Le procédé selon l'invention comporte les étapes suivantes.The method according to the invention comprises the following steps.
On fait fondre l'alliage et on le porte à une température plus élevée que la température de fusion d'environ 80 à 180° C de manière à obtenir une viscosité appropriée. On forme à partir du liquide un jet qui traverse une buse calibrée. Le jet est ensuite pris en compte par une tuyère supersonique où il est soumis à des zones d'accélération et des zones de dépression provoquées par des jets de gaz inertes sous hautes pression.The alloy is melted and brought to a temperature higher than the melting temperature of about 80 to 180 ° C so as to obtain an appropriate viscosity. A jet is formed from the liquid which passes through a calibrated nozzle. The jet is then taken into account by a supersonic nozzle where it is subjected to zones of acceleration and zones of depression caused by jets of inert gases under high pressure.
Les particules métalliques sont sur-refroidies par contact avec un gaz sous haute pression ou un solide . La vitesse de refroidissement varie entre 10⁶ et 10⁸ ° C/s. On obtient ainsi une poudre dont les dimensions de grains varient de 0 à 50 µ ou de 0 à 120 µ selon les paramètres.The metal particles are super-cooled by contact with a gas under high pressure or a solid. The cooling rate varies between 10⁶ and 10⁸ ° C / s. A powder is thus obtained whose grain sizes vary from 0 to 50 μ or from 0 to 120 μ depending on the parameters.
La poudre obtenue selon le procédé décrit ci-dessus avec une vitesse de refroidissement supérieure à 10⁶ ° C/s comporte des grains de silicium de moins de 1 µ ou de silicium à l'état de solution solide.The powder obtained according to the method described above with a cooling rate greater than 10⁶ ° C / s comprises grains of silicon of less than 1 μ or of silicon in the state of solid solution.
La production de poudre s'effectue dans une enceinte hermétique à double parois afin d'éviter l'oxydation.Powder production takes place in an airtight double-walled enclosure to prevent oxidation.
La poudre ainsi obtenue est recueillie dans un récipient en aluminium ou alliage à paroi très fine sand précompression, sous vide.The powder thus obtained is collected in an aluminum or alloy container with a very thin precompression sand wall, under vacuum.
On procède ensuite à l'extrusion dans une filière en chauffant exclusivement l'outil à une température au plus égale à 350°C. La poudre avec son pot sont engagés conjointement dans la filière et extrudés en tubes ou en barres. Le pot qui est en aluminium pur ou en alliage réalisé par le même procédé n'introduit pas de perturbation dans la composition de l'alliage et surtout n'introduit pas de grains de silicium de dimension supérieure à 1 µ . La dimension du pot est choisie pour un coefficient de réduction dans la filière compris entre 10 et 20 préférentiellement pour un coefficient de réduction de 13.Extrusion is then carried out in a die by exclusively heating the tool to a temperature at most equal to 350 ° C. The powder with its pot are jointly engaged in the die and extruded into tubes or bars. The pot which is made of pure aluminum or an alloy produced by the same process does not introduce any disturbance in the composition of the alloy and above all does not introduce silicon grains of dimension greater than 1 μ. The size of the pot is chosen for a reduction coefficient in the sector between 10 and 20 preferably for a reduction coefficient of 13.
