The phenomenon of precipitation hardening was first discovered in an al–4cu–0.6mg (wt.%) alloy by the german chemist alfred wilm in 1906. one of the most widely used alloys in the aeronautical industry is 2024 (al–4.2cu–1.5mg–0.6mn (wt.%)), which was introduced in the 1930s. when ageing is performed at a sufficiently low temperature.

Alexopoulos et al. [8] reported the precipitation kinetics, yield strength and work hardening behaviour of an al cu mg alloy, and found that both yield strength and work hardening behaviour were. Precipitation in stretched al cu mg alloys with reduced alloying content studied by dsc, tem and atom probe. the hardening and microstructural evolution during ageing of a al 1.2cu 0.5mg and a al 1.2cu 1.2mg (at.%) alloy has been investigated. artificial ageing at 150°c of stretched and naturally aged…. In this paper, the effect of two step precipitation hardening on the mechanical properties of al 3.7cu 1mg was investigated. for this meaning, some specimens were subjected to the first step aging at 175, 190 and 205 °c for 2 h, once the samples solution treated at 500 °c.

The topic of precipitation hardening is critically reviewed, emphasizing the influence of precipitates on the crss or yield strength of aged alloys. recent progress in understanding the statistics of dislocation precipitate interactions is highlighted. it is shown that pythagorean superposition for strengthening by random mixtures of localized obstacles of different strengths is rigorously. Precipitation hardening, or age hardening, refers to a mechanism that takes place at the artificial ageing stage of a heat treatment process, which is commonly used to improve the mechanical properties of commercial aluminium alloys. it is only applicable to heat treatable aluminium alloys. view chapter explore book.
