Precipitation Hardening of Aluminum Alloys :: Total Materia ...

The strongest aluminum alloys (2xxx, 6xxx and 7xxx) are produced by age hardening. In order for an alloy system to be able to be precipitation-strengthened, there must be a terminal solid solution that has a decreasing solid solubility as the temperature decreases.

Aluminum and Aluminum Alloys - materialsdata.nist.gov

Aluminum alloys are second only to steels in use as structural metals. Aluminum has a density of only 2.7 g/cm3, approximately one-third as much as steel (7.83 g/cm3). One cubic foot of steel weighs about 490 lb; a cubic foot of aluminum, only about 170 lb. Such light weight, coupled with the high strength of some aluminum alloys (exceeding that of struc-

Precipitation hardening - Wikipedia

Elements used for precipitation strengthening in typical aluminium and titanium alloys make up about 10% of their composition. While binary alloys are more easily understood as an academic exercise, commercial alloys often use three components for precipitation strengthening, in compositions such as Al(Mg, Cu) and Ti(Al, V).

Precipitation strengthening of aluminum alloys by room ...

High-strength aluminum alloys are important for lightweighting vehicles and are extensively used in aircraft and, increasingly, in automobiles. The highest-strength aluminum alloys require a series of high-temperature “bakes” (120° to 200°C) to form a high number density of nanoparticles by solid-state precipitation.

Precipitation hardening of aluminum alloys | SpringerLink

Precipitation hardened aluminum alloys do not have good elevated temperature properties because the hardening precipitates normally used, GP zones, are not stable at elevated temperatures. Thus a low interfacial energy, ductile precipitate, which is stable at elevated temperatures, is needed for aluminum.

Aluminium alloy - Wikipedia

7000 series are alloyed with zinc, and can be precipitation hardened to the highest strengths of any aluminium alloy (ultimate tensile strength up to 700 MPa for the 7068 alloy ). Most 7000 series alloys include magnesium and copper as well.
