Precipitation strengthening at ambient and elevated temperatures of heat-treatable Al(Sc) alloys
TLDR
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.About:

A precipitation-hardened high-entropy alloy with outstanding tensile properties
Junyang He,Hao Wang,He Huang,Xiandong Xu,Mingwei Chen,Yuan Wu,Xiongjun Liu,T.G. Nieh,Ke An,Zhaoping Lu +9 more
TL;DR: In this paper, the authors demonstrate the possibility to precipitate a coherent reinforcing phase in a fcc-FeCoNiCr HEA matrix using minor additions of Ti and Al, and demonstrate that extraordinary balanced tensile properties at room temperature were achieved, which was due to a well combination of various hardening mechanisms, particularly precipitation hardening.

The Hardness of Metals
TL;DR: Hardness measurements with conical and pyramidal indenters as mentioned in this paper have been used to measure the area of contact between solids and the hardness of ideal plastic metals. But they have not yet been applied to the case of spherical indenters.
