Definitions

  • ALUMINUM-ZINC-ALLOY Inventors: Gilbert l-lorvath, Linz, Austria;
  • the invention relates to an aluminum-zinc-alloy consisting of 50 to 75 aluminum, 0.3 to 1.5 manganese and, if desired, copper, nickel, silicium, lithium and chromium, remainder zinc.
  • these new alloys are provided with an increased red hardness, high load sustaining capacity at sliding movement, lasting accuracy to gauge, high mechanical strength, adequate resistance to corrosion, essentially increased resistance to creeping, increased applicability as casting and kneading material, and may be hot shaped at high working speeds with temperatures of the range 275 to 450 C.
  • the invention relates to an aluminum-zinc-alloy containing manganese and, if desired, further alloy elements such as copper, nickel, silicium, lithium and chromium.
  • Aluminum-zinc-alloys consisting of aluminum and zinc in various contents, manganese and, if desired, further alloy elements, which are used as materials for slide bearings are already known.
  • the invention is aimed at avoiding the described disadvantages and difficulties by creating an alloy which unites the following properties: increased red hardness (that is, hardness at elevated temperatures) as compared to known bearing alloys on aluminum-zinc-basis, high load sustaining capacity at sliding movement, lasting accuracy to gauge, high mechanical strength, adequate resistance to corrosion, essentially increased resistance to creeping as compared to known aluminumzinc bearing alloys, increased applicability both as material for casting and kneading (re-shaping operations). Further, the alloy should be hot shapeable at high working speeds, similar as this is the case with bronzes.
  • the alloy according to the invention with which these aims are reached is an aluminum-zinc-alloy containing 50 to 75 preferably 55 to 65 aluminum, 0.3 to l .5 preferably 0.5 to 0.8 manganese, and, if desired,
  • This alloy differs from other known alloys having a comparably high aluminum content in that its manganese content is limited at a maximum of
  • the effect of the manganese content in the aluminum-zinc-alloy is based on the high inclination of the aluminum-zinc solid solution to be oversaturated with manganese during the rapid solidification under normal production conditions (particularly chill casting). Owing to this capacity (of the aluminum-zinc solid solution) to be oversaturated, it is e.g. effected that the manganese remains in solution but only to a particular, low percentage which again depends on the content of other alloy elements and does not form hard aluminides.
  • manganese increase of tensile strength, yield point, elongation, resistance to wear, red hardness and resistance to corrosion.
  • the manganese addition within the limits according to the invention furnishes an alloy on aluminum-zinc-basis with properties which are otherwise not obtainable or only with essentially more expensive alloys. Owing to the high content of aluminum of the alloy according to the invention and the therefore only very small change in volume during the eutectic transformation of the aluminumzinc mixed crystal it is possible and advantageous to carry out heat treatments also above a temperature of 275 C without the occurrence of an embrittlement in the material.
  • the copper content of the alloy according to the invention may amount to up to 3
  • the nickel content of the alloy according to the invention may amount to up to 1
  • the silicium content of the alloy according to the invention may amount to up to 0.6
  • the lithium content of the alloy according to the invention may amount to up to 0.1
  • the chromium content of the alloy according to the invention may amount to up to 0.5
  • a preferred embodiment for producing shaped bodies from alloys of the described kind by hot shaping resides in that a shaping temperature of 275 to 450 C, preferably of 330 to 350 C, is applied. Owing to the higher temperature for hot shaping it is possible to work with an essentially higher shaping speed than may be employed with known alloys. Shaping may also be effected by extrusion, traction and rolling.
  • the shaped bodies may also be produced from the described alloys by casting and subsequent heat treatment, the heat treatment being carried out at a temperature of 290 to 380 C, preferably 330 to 350 C.
  • the duration of the heat treatment may amount to several hours up to 48 hours.
  • an alloy of the following composition is produced which is used for manufacturing a bearing bushing with an inner diameter of 30 mm and an outer diameter of 40 mm.
  • the alloy is composed of:
