TLDR
In this paper, the authors correlated the monotonic and cyclic properties of three AlLi alloys with the slip behavior and found that cracks nucleated at grain boundary ledges during tensile tests and propagated either transgranularly or intergranularally along precipitate free zones.About:

Precipitation strengthening at ambient and elevated temperatures of heat-treatable Al(Sc) alloys
TL;DR: In this article, the authors investigated yield strength at ambient temperature and creep resistance between 225 and 300°C in dilute Al(Sc) alloys containing coherent Al3Sc precipitates, which were grown by heat-treatments to radii in the range 1.4-9.6 nm.

Strength, deformation, fracture behaviour and ductility of aluminium-lithium alloys.
TL;DR: In this paper, the deformation characteristics and fracture behavior of aluminium alloys are examined with specific reference to ageing condition of the alloy, the matrix slip characteristics, and the nature, volume fraction and distribution of strengthening precipitates.

Microstructural control of toughness in aluminium-lithium alloys
P.J. Gregson,H.M. Flower +1 more
TL;DR: In this paper, the deformation behavior of Al-Li-based alloys containing zirconium as a grain-refining addition is investigated, and it is shown that the poor toughness properties are attributed to the intense coplanar slip associated with δ' (Al3Li) precipitation being unimpeded by the grain structure as a result of the pronounced deformation texture present in the sheet product.

Effects of cold work on precipitation in Al-Cu-Mg-(Ag) and Al-Cu-Li-(Mg-Ag) alloys
TL;DR: In this paper, the effects of cold work prior to aging on precipitation hardening in selected Al-Mg-(Ag) and Al-Cu-Li-(Mg-Ag) alloys were investigated.

Metallurgical factors affecting fracture toughness of aluminum alloys
G. T. Hahn,A. R. Rosenfield +1 more
TL;DR: The fracture toughness of aluminum alloys depends on a) the extent of the heavily strained region ahead of the crack tip, which is a function of the yield strength arad modulus, b) the size of the ligaments which is related tof c, the volume fraction of cracked particles, and c) the work of rupturing ligaments.

On the strength of solid solution alloys
TL;DR: In this paper, it was shown that motion of a dislocation through a crystal with short-range order partially destroys the order and produces an interface of positive mean energy γ per unit area, an additional stress τ = γ b is required to force the dislocation along the slip plane.

Precipitation Characteristics of Aluminium-Lithium Alloys

TL;DR: In this paper, structural ageing characteristics of aluminium alloys containing 2 and 4 wt.-% lithium are reported and thin-film electron microscopy was used to confirm the ordered L12-typestructure of the δ′ and to study the precipitate size and distribution over a range of ageing temperatures.
