Definitions
- the alloys mentioned have been developed for obtaining semi-finished products (billets or ingots for forging or rolling) intended to be transformed during hot or cold operations with high deformation rates (> 50%).
- the geometries of these semi-finished products are simple (bar, bar or ingot) which makes it possible to solidify these alloys with a minimum of defects by using processes with high solidification rates.
- These geometries and these processes lead, according to currently controlled techniques, to semi-finished products free from defects among which we can mention: shrinkage, cracks, macro-segregations, macro-precipitation (prevents the formation of too coarse precipitates,> 100 ⁇ ).
- the magnesium level is between 0, 65 and 1%. This rate makes it possible to optimize the density of Mg 2 Si precipitates in the aluminum matrix. It compensates for the decrease in silicon content while having a minimum of macroscopic Mg 2 Si precipitates that are damaging and must be dissolved or transformed during heat treatment. If the precipitates are too numerous, or too big, the heat treatment will have a weak effect for their dissolution, the critical size of dissolution having been exceeded.
- the copper content is between 0.20 and 0.40%. This rate allows the formation of Al 2 Cu precipitates in the matrix and the total absence of macroscopic Al 2 Cu precipitates. The absence of these macroscopic precipitates makes it possible to maintain high forging temperatures and thus to minimize forging efforts (which is carried out in a single step). Indeed, the main precipitates formed in the presence of copper are Al 2 Cu and AlMgSiCu respectively melting at 490 ° C and 525 ° C, their presence would prevent forging at higher temperatures without risk of burning of the alloy that would make the parts unusable. This degradation is similar to a destruction of the alloy.
- a higher copper content also increases the crack sensitivity of the alloy, because there remains a eutectic to be solidified at low temperatures (490 ° C or 525 ° C) for which the mechanical stresses (related to the removal of solidification) exercised on the piece are important.
- the manganese content is between 0.15 and 0.25%. This rate avoids the formation of AlFeSi precipitates in ⁇ -form (very damaging plate) and makes it possible to form AlFeMnSi precipitates in a form (less damaging Chinese writing). This maximizes the finished part elongation resulting from the Cobapress process. This effect is most often used with larger amounts of manganese and iron, these two elements leading to a hardening of the alloy but also to larger precipitates during solidification.
