Definitions
- the aluminum alloys which con- In the process according to the invention a quantity of tain magnesium and silicon are capable of being given tin between 0.001 and 0.1 percent and. preferably between improved mechanical properties by quenching from atem- 0.005 and 0.1 percent is added to the aluminum alloy perature at which the metal is entirely or almost entirely containing magnesium and silicon.
- Typical alloys accordin the state of solid solution. This rapid cooling is then ing to the invention have the following compositions: followed by a natural or artifical aging.
- Such alloys are magnesium 0 2 to 2% employed either in the cast state or in the transformed si1ic0n 0 2 to'5% state obtained by operations resulting from hot working to 0.1%: or h Such. as forgmg forming rohihg impurities-iron up to 0.5%, others up to 0.2% each, trudlng drawlng and wire-drawing.
- the mechamcal characteristlcs obtained after quenchaluminum balance ing and artifical aging, or tempering, are proportionally higher for a quenching of given intensity when the time pfeferredhhow whlch are modlfieh 1h accordahfie Wlth elapsed between these two operations is shorter. It is the 1115mm lhventlon have the f llowing compositions;
- tin is added in amounts of 0.01 percent and 0.1 percent to an alloy, the composition of which is as follows:
- the alloy to which no tin is added and the two alloys containing the addition are cast into billets, then extruded under the same conditions Without previous homogenization of the billets.
- the bars which are obtained are heated for two hours to 560 C., and then quenched in water. They are then subjected to an annealing operation which lasts hours at a temperature of 175 C. The annealing is conducted either immediately after the quenching or after an increasingly long period of time.
- tion are suitable for use in combination with a wide variety of aluminum-magnesium-silicon alloys.
- the fol- 4 lowing comprises a list of additional elements which may be included in such alloys and which will not affect the improvements provided by the tin additions:
- alloys of the type described can be utilized. It will be apparent, however, that such additions are contemplated only where they do not interfere with the function of the tin additions described herein.
- magnesium is present in said alloys in amounts between 0.4 and 1.0 percent by weight
- silicon is present in said alloys in amounts between 0.4 and 0.8 percent by weight
- aid iron is present in said alloys in amounts up to 0.5 percent by weight.
- alloys contain up to 6 percent by weight manganese, up to 6 percent by weight chromium, up to 1 percent by weight titanium, up to 1 percent by weight zirconium, up to 1 percent by weight vanadium and up to 0.1 percent by weight boron.
