Definitions
- the invention relates to the field of aluminum-silicon-copper alloys, which can possibly contain other additives such as magnesium, cast in the form of billets having a globular solidification structure conferring thixotropic properties and intended to be shaped, by forging or injection under pressure, after reheating in the semi-solid state.
- Such shaping is known as thixoforming
- Thixoforming developed from the discovery made in the early years 1970 by the team of Pr FLEMINGS at MIT that a metal, developed in some particular conditions, presents, when it is reheated in the semi-solid state, a apparent viscosity which strongly depends on the shear rate, so that it behaves like a solid during handling and like a liquid viscous when injected into a mold. This property leads, compared to traditional shaping processes, better metallurgical quality of parts produced, higher production rates, less wear of tools and molds and energy saving.
- the solidification of the metal with thixoforming must lead to a structure globular, not dendritic, which can be obtained either by mechanical agitation of the solid-liquid mixture as in US Patent 3,948,650 of the MIT, either by mixing electromagnetic as in US patents 4434837 and US 4457355 of ITT-ALUMAX or the patents EP 0351327 and EP 0439981 of ALUMINUM PECHINEY.
- the billets thus cast are cut into pieces corresponding to the quantity of metal necessary for the manufacture of the part to be formed, these pieces being heated to the semi-solid state, usually by induction heating, and transferred to shaping equipment (forging press or pressure injection machine).
- alloys intended for thixoforming to increase the resistance of the parts produced, or to facilitate machining, tried to use alloys containing 1 to 5% copper. With for example a alloy with 3% copper, no particular problem is encountered with the casting of billets, and the mechanical resistance at the level of the billet is effectively improved more than 25%. If the reheating temperature is adjusted to the semi-solid state, by lowering it by a few degrees C, to stay at a liquid fraction rate close to 50%, the thixoforming of this alloy is also easy.
- the invention aims to find a field of composition of aluminum-silicon alloys more than 5% silicon and containing 1 to 5% copper allowing get out of the dilemma set out above, i.e. allow both thixoforming without problem and to obtain parts having a high mechanical resistance and a good elongation.
- the subject of the invention is the use of an aluminum alloy of composition (% by weight): If: 5% - 7.2% Cu: 1% - 5% Mg ⁇ 1% Zn ⁇ 3% Fe ⁇ 1.5% other elements ⁇ 1% each and 3% in total, aluminum remains, such as:% Si ⁇ 7.5 - (% Cu / 3), for forming in the semi-solid state, at a rate of liquid fraction included between 35% and 55%, and with, in this state, a structure free of polyhedral crystals not remelted silicon.
- the single figure represents, in a diagram having for abscissa the content of silicon and for ordinate the copper content, the lines of equal eutectic fraction and the composition domain according to the invention.
- the alloys according to the invention remain in the usual composition ranges of AlSiCu molding alloys. We do not go below 5% silicon because the alloy becomes difficult to flow.
- the addition of copper has a significant effect on the mechanical strength and the machinability only from a content of approximately 1% and, beyond 5%, there is a very unfavorable effect on the elongation .
- Magnesium in a content of less than 1%, increases the response to heat treatment thanks to the formation of hardening particles Mg 2 Si, but, beyond 1%, there is also an unfavorable effect on the elongation.
- a eutectic silicon modifier such as sodium, strontium or antimony, which prevents the formation of coarse grains of silicon Sodium and strontium can be present alone or together, antimony being always alone.
- strontium for example, the content is between 0.005 and 0.05%.
- titanium up to 0.2% and / or boron up to 0.1%, allows a refinement of the grain and a better heat resistance.
- an alloy Ai-Si6Cu3Mg0,6 or a Al-Si6,5Cu1,5Mg0,6 alloy have a thixoforming behavior identical to that of an Al-Si7Mg0.6 alloy, that is to say that a rate of liquid fraction close to 50% with a complete fusion of the eutectic, and therefore a absence of polyhedral silicon crystals.
- the metal loss was 8 ⁇ 2%, identical to that of the alloy Ai-Si7Mg0.6.
- the apparent viscosity of pieces heated at a temperature between 2 and 5 ° C. above the eutectic plateau was measured, using a penetration test consisting in measuring the resistance to deformation F of the heated piece compressed by a tool at constant speed at the end of a stroke of determined length.
- the ratio of this force F to a constant threshold force F s is established , for a conventional value of metal loss by exudation of 8%, the metal loss being an indicator of the rate of liquid fraction for a given material.
- the rate of liquid fraction is controllable to within ⁇ 5%, taking into account the usual silicon content intervals allowed by the standards and specifications for the alloys considered, it can be estimated that, in the figure, the composition of the alloy must be such that the Si and Cu contents satisfy the relation: (2) 6.5 -% Cu / 3 ⁇ % Si ⁇ 7.5 -% Cu / 3 which corresponds to the fact that the rate of liquid fraction obtained with complete fusion of the eutectic is between 45 and 55%, or that the eutectic fraction of the alloy is between 45 and 55%.
- the thixoforming behavior is poor: as soon as the filling of the mold cavity begins, the heat loss by exchange with the mold wall leads to partial resolidification and an increase in the apparent viscosity which causes defects in the part. injected, such as folds, shrinkage or non-arrival.
- the range corresponding to the compositions according to the invention comprises not only the band between the straight lines representing the eutectic fractions of 55% and 45%, i.e. the fringe surrounding the straight line representing 50%, but also the area between 45% and 35% which, taking into account the lower limit of Cu to 1 %, practically corresponds to the adjacent triangle.

Description
Ainsi, en se reportant à la figure représentant les teneurs en silicium et cuivre, sur laquelle on a fait figurer les droites d'égale fraction eutectique, on constate que le domaine correspondant aux compositions selon l'invention comprend non seulement la bande comprise entre les droites représentant les fractions eutectiques de 55% et 45%, c'est à dire la frange entourant la droite représentant 50%, mais aussi la zone comprise entre 45% et 35% qui, compte-tenu de la limite inférieure de Cu à 1%, correspond pratiquement au triangle adjacent.
