Definitions
- the invention relates to a method for obtaining an Al alloy of the 7000 series (Al-Zn-Mg-Cu) with high mechanical strength and good ductility by "spray-deposition" (spray deposition). More specifically, the method aims to obtain Al alloys which have in the treated state (T6) a breaking load ⁇ 800 MPa with an elongation, at least in the long direction, greater than or equal to 5%.
- the invention also relates to obtaining composite materials with very high strength, high rigidity and good ductility having as matrix the 7000 alloys described above with a particulate reinforcement of ceramics and obtained directly by "spray-deposition".
- spray-deposition is meant a process in which the metal is molten, atomized by a jet of gas at high pressure in the form of fine liquid droplets which are then directed and agglomerated on a substrate so as to form a massive and coherent deposit, containing a low closed porosity.
- This deposit can be in the form of billets, tubes or plates whose geometry is controlled.
- a technique of this type is known as “Spray Deposition” by the Anglo-Saxons and is also called “OSPREY process”.
- the volume fraction of precipitates at the base of the structural hardening of the alloy (essentially of the type ⁇ -Mg Zn2 or ⁇ '- (Mg, Zn, Al, Cu)) becomes insufficient and it is no longer possible to obtain the levels of high mechanical characteristics (such as breaking load ⁇ 800 MPa) which are the objective of the present invention.
- the volume fraction of the second phase is too high and leads to a brittle material, with very low elongations at break, which prohibits its industrial use.
- the copper and magnesium contents must be in proportions close to the stoichiometry of the hardening precipitates.
- Mg ⁇ 2% or Cu ⁇ 0.5% the nature and the volume fraction of the precipitates formed are insufficient to achieve the targeted mechanical characteristics.
- Mg is ⁇ 4% or Cu ⁇ 2.0%, these elements are present in excess in the alloy and weaken it considerably.
- the content of main elements preferably obeys the following relationship, 5.5 ⁇ Mg + Cu + Zn 6 ⁇ 6.5
- the hot transformation of the solid alloy obtained by spray-deposition generally takes place between 300 and 450 ° C, preferably by spinning, forging or rolling, in one or more successive operations; these operations can optionally be combined, for example spinning + rolling or spinning + forging / stamping.
- the hot transformation operations can be supplemented by cold operations such as rolling, drawing, etc.
- the solution is carried out between 440 and 520 ° C, between 2 and 8 hours depending on the size of the products; quenching is followed by tempering between 2 and 25 h between 90 and 150 ° C in one or more stages, the longest times being generally associated with the lowest temperatures (and vice-versa).
- the product obtained by a spray-deposition process can optionally be homogenized before hot transformation between 450 and 520 ° C for 2 to 50 hours in one or more stages.
- the invention also consists, using the alloys and the method described above, in obtaining composite materials with very high resistance (Rm ⁇ 800 MPa), high Young modulus (E ⁇ 80 GPa), with acceptable ductility by users (A ⁇ 3%), as well as good resistance to wear and friction.
- These materials are characterized by an alloy matrix of the 7xxx series of composition indicated above and a dispersion of ceramic particles of SiC, Al2O3 or B4C type (these examples not being limiting) and are obtained directly by the spray-deposition technique.
- the alloys n ° 1 to 4 according to the invention have a very high level of mechanical characteristics, with in particular a breaking load ⁇ 800 MPa as well as a correct level of ductility, with elongations at break ⁇ 5% .
- Alloy 5 outside the analytical limits of the invention (Zn content too low) has much weaker mechanical characteristics than the alloys of the invention.
- Alloy 8 is an alloy whose composition falls within the analytical field of the alloys of the invention but which has been developed according to a powder metallurgy process described below: the alloy is melted and then atomized with nitrogen in the form powders; these are collected and sieved to 100 ⁇ m. Powders smaller than 100 ⁇ m are put in 140 mm diameter aluminum containers fitted with an orifice tube and are then degassed hot under secondary vacuum (by pumping through the tube) at a temperature of 460 ° C for 100 h. The powder containers thus degassed are sealed and then hot pressed in a blind die spinning press in a 143 mm diameter container at 450 ° C so as to reach the theoretical density of the material.
- the billets thus obtained are then machined in order to remove the material from the container and then spun under the same conditions as the billets of the previous examples.
- the product obtained is heat treated according to a similar procedure (see solution temperature in Table 1) and is characterized under the same conditions.
- the results reported in Table 1 show that the product obtained has very low ductility and plastic deviation despite a relatively high level of resistance.
- An alloy of composition Al Al: 10% Zn; 3.0% Mg; 1.0% Cu; 0.1% Zr; 0.15% Cr; 0.15% Mn, rest Al was melted at 750 ° C and produced by spray-deposition in the form of 150 mm diameter billets with simultaneous coinjection of SiC particles of average size 10 ⁇ m, with a volume fraction of 15%.
- the billets thus obtained are then peeled to ⁇ 140 mm, homogenized for 8 hours at 470 ° C, hot-spun at 400 ° C in the form of flats of section 50 x 22 mm (spinning ratio 14.6).
