Definitions
- the present invention relates to a process for manufacturing parts made of aluminum alloy retaining good resistance to fatigue after prolonged hot keeping.
- aluminum has the particular property of being three times lighter than steel and of having good corrosion resistance. By combining it with metals such as copper and magnesium, its mechanical resistance is greatly improved. Furthermore, the addition of silicon gives a product having good wear resistance. These alloys doped with other elements such as iron, nickel, cobalt, chromium and manganese, see their heat resistance improved. A compromise between these addition elements makes aluminum a material of choice for the manufacture of parts for automobiles such as engine block, piston, cylinder, etc.
- EP 144898 teaches an aluminum alloy containing by weight 10 to 36% of silicon, 1 to 12% of copper, 0.1 to 3% of magnesium and 2 to 10% of at least one element chosen from the group Fe, Ni, Co, Cr and Mn.
- This alloy is applicable to the manufacture of parts intended for both the aeronautical and automotive industries, said parts being obtained by the technique of powder metallurgy comprising, in addition to shaping by compacting and spinning, an intermediate processing step thermal between 250 and 550 ° C.
- Document JP-A-6342344 is also known, which teaches an aluminum alloy with excellent mechanical properties at high temperature by powder metallurgy, characterized in that it consists of Si, Fe, Cu, Mg and Mn in the weight proportions. 12 ⁇ If ⁇ 28%, 2.0 ⁇ Fe ⁇ 10%, 0.8 ⁇ Cu ⁇ 5.0%, 0.3 ⁇ Mg ⁇ 3.5% and 0.5 ⁇ Mn ⁇ 5%, of one or more elements chosen from Zr, Hf, Ni, Ti, V, Cr , Mo, Nb and Ta in a proportion by weight of 0.02 - 2.0% and, for the rest, of aluminum and inevitable impurities. But here, as in the previous document, no mention is made of the fatigue resistance properties after being kept for 1000 hours at 150 ° C. and the range of manganese content is relatively wide.
- the Applicant has noticed that if the zirconium brought a significant improvement from the point of view of the fatigue limit at 20 ° C, since it went from 150 to 185 MPa, on the other hand, after a maintenance of 1000 hours at 150 ° C (which roughly represents the working conditions of a connecting rod at mid-life of an engine), that limit dropped to 143 Mpa, a reduction of more than 22%.
- the present invention which consists of a process for manufacturing aluminum alloy parts obtained from the alloy in the state melted by a means of rapid solidification, retaining a suitable resistance to fatigue after prolonged keeping hot which contain by weight 11 to 26% of silicon, 2 to 5% of iron, 0.5 to 5% of copper, 0, 1% to 2% magnesium, zirconium, at least 0.5% manganese, optionally minor additions of nickel and / or cobalt and the aluminum balance, characterized in that an alloy containing 0.1 to 0.4% of zirconium and up to 1.5% of manganese is used.
- manganese has been substituted for part of the zirconium, which on the one hand allows savings on raw materials: manganese being cheaper than zirconium , on the other hand facilitates the melting conditions of the alloy since a binary alloy containing 1% of zirconium has a liquidus temperature of 875 ° C whereas if it is 1% of manganese this temperature remains close 660 ° C.
- the invention is also characterized in that the alloy is subjected in the molten state to a rapid solidification means before putting it in the form of parts.
- a rapid solidification means before putting it in the form of parts.
- elements such as iron, zirconium and manganese are very little soluble in the alloy, it is essential to obtain parts meeting the desired characteristics to avoid a rough and heterogeneous precipitation of these elements what we achieves by cooling them as quickly as possible.
- the alloy is preferably melted at a temperature above 700 ° C so as to avoid any phenomenon of premature precipitation.
- the parts after being possibly subjected to machining, are heat treated between 490 and 520 ° for 1 to 10 hours, then quenched in water before undergoing a tempering treatment between 170 to 210 ° C for 2 to 32 hours, which improves their mechanical characteristics.
- the combination of zirconium-manganese in limited quantities and the rapid solidification of the alloy obtained contribute to improving the resistance to fatigue, whether cold or hot, of parts liable to exhibit irregularities. surface like threads or connection curves and which find their application in the automobile industry, in particular in the confection of rods, axes of pistons and pistons.
