Influence of Martensite Deformation on Cu Precipitation Strengthening

open access: yesMetals, 2020
Cu precipitation strengthening was compared in steels after treatments with and without cold rolling. A 0.2% C steel containing up to 1.5% Cu was quenched and tempered.

Assessing the predictive capabilities of precipitation strengthening models for deformation twinning in Mg alloys using phase-field simulations

open access: yesJournal of Magnesium and Alloys, 2023
Precipitation strengthening is a key strategy for improving the overall mechanical properties of Mg alloys. In Mg-Al alloys, basal precipitates are known to strengthen against twinning, resulting in an increase in the critical resolved shear stress (CRSS)

On the theory of strengthening by coherent ordered precipitates [PDF]

open access: yesPhilosophical Magazine Letters, 1990
Abstract This paper contrasts recent discussions of the theory of strengthening by coherent precipitates. The most important difference is in the assumed condition at maximum hardness. In one treatment, the maximum hardness is reached when dislocations first begin to loop precipitates, and is hence controlled by the largest particles in the precipitate

An intercomparison of global oceanic precipitation climatologies [PDF]

open access: yes, 2007
Large-scale patterns of precipitation are important for the changes they may effect upon the circulation of the ocean. However, marine precipitation is very hard to quantify accurately.
