Description
Technical Field
The invention relates to a casting alloy based on aluminium, iron and nickel with the addition of boron. The invention also relates to the use of the alloy for high pressure die casting or gravity die casting. The alloy of the invention is used for producing rotors and stators for electric motors and heat exchangers, cooling and heating elements in the electronics industry or in vehicle construction.
Background
The use of rotor aluminum (e.g., 99.7% aluminum by mass) in high pressure die casting has long been known. Typically, the metal body is placed in a die casting mold and an aluminum rotor or stator is cast inIn the metal body. In this way, difficulties in casting such alloys are avoided, in particular the tendency to stick to the steel, which would otherwise lead to rapid wear of the mould. Other typical disadvantages are high shrinkage, extremely high casting temperatures, poor machinability and particularly low strength (e.g. for Al alloys) 99.7 E, rp0.2 is 20-40 MPa).
For heat exchangers produced by high-pressure die casting, alloys of the AlSi type, for example the alloy AlSi, are generally used 9 Sr (Castasil-21). These alloy types are more castable than rotor aluminum. The tendency to stick to the casting mould, shrinkage, mould filling and casting temperature are all the more favourable. However, the lower electrical and thermal conductivity is disadvantageous compared to rotor aluminum. By heat treatment, an electrical conductivity of up to 28MS/m can be achieved, followed by a thermal conductivity of 190 (W/K m). The yield strength (Rp0.2) of the alloy is 80-100MPa.
The patent EP 3 235 916 B1 of the applicant discloses an AlMg 4 Fe 2 (castreduce-42) type alloy, preferably for crash related structural components in automotive construction. The metallurgical basis of this alloy is Al 3 And (4) eutectic crystallization of Fe. The conductivity is 16-17MS/m.

According to another aspect of the invention, the cast alloy is used for high pressure die casting, preferably for rotors and stators for electric motors and heat exchangers, cooling and heating elements in the electronics industry or vehicle construction.
A high-pressure die-cast product, preferably for rotors and stators of electric motors and heat exchangers, cooling and heating elements in the electronics industry or in vehicle construction, made from the cast alloy according to the invention.
The castability of the alloy according to the invention is achieved by adding the alloying elements iron and nickel so as to form a eutectic phase (which improves the castability of the alloy). In particular, al should be obtained 9 The FeNi phase, according to the literature, is produced in an ideal ternary system having a composition of 1.75wt% Fe and 1.25wt% Ni. In the case of alloy variants, al may also be present 3 Fe or Al 3 A Ni phase. Al (aluminum) 3 The Ni phase has a high Ni content and a low Fe content.
According to the invention, the Fe content should be high and with a smaller amount of Al 3 Fe eutectic crystal promotes Al together 9 And forming FeNi. This reduces the tendency for the alloy to stick and improves castability.
Al 9 FeNi、Al 3 Fe and Al 3 Three phases of Ni in the micrographAll showed very fine long fibers and had similar eutectic temperatures (640 ℃, 650 ℃ and 655 ℃). Thus, they are generated almost simultaneously and at almost the same location during the casting process, which may result in mixing of these phases. Industrially produced die-cast parts also exhibit a number of structural defects. Thus, the three phases (Al) 9 FeNi、Al 3 Fe and Al 3 Ni) are often difficult to distinguish in micrographs.
The alloy according to the invention is hardly reactive to heat treatment, as long as no further elements are added. Thermal treatment can have a positive effect on electrical and thermal conductivity. The metallurgical background is mainly the agglomeration of the additional elements and the coarsening of the phases, which results in a better conductivity of the α -Al.
The strength of the alloy may be increased by adding additional alloying elements.
In general, solid solution strengthening of the α -Al phase should be achieved. However, in general, such solid solution strengthening often leads to a reduction in conductivity, which is why even only certain elements are considered.
The Si content should not exceed 0.4% to ensure Si-free eutectic. To this level, it is expected that only the α -Al phase is enriched, which may slightly increase the strength.
The addition of about 40-300ppm boron results in a slight increase in conductivity. The metallurgical background is the formation of borides, which can reduce the negative effects of impurities. On the one hand, such borides can be expelled during degassing, and on the other hand, they can lead to an accumulation of impurities, resulting in a higher electrical conductivity (electrical and thermal conductivity).
The element for improving strength is Mg. It does not form a phase with Fe, has high solubility in α -Al, but has a negative effect on electrical conductivity (electrical and thermal conductivity). In addition, phases containing MgNi can form, which can interfere with Al 9 Formation of FeNi phase. Therefore, the alloy according to the invention should contain no or only a small amount of Mg, preferably at most 0.6%.
If Si is present in the alloy, mg is formed 2 Si phase (or one of its metastable variants), thereby increasing strength. Further heat treatment becomes possible。
Zn is known to increase the strength of the alloy according to the invention and its negative impact on electrical conductivity (electrical and thermal conductivity) is limited. However, if Mg is not added, the strength cannot be significantly improved. If Mg and Zn are added simultaneously, the material becomes hard and the strength increases.
Another strength-enhancing element in aluminum is Cu. Its negative impact on conductivity is less than Mg. However, only a small amount of Mg added to Cu can significantly improve the strength.
Other elements which may have a strength-increasing effect are Sn, mn, cr, li, V, ti, ca, ga, bi, mo and Zr.
