Understanding the effect of cobalt on the precipitation hardening behavior of the maraging stainless steel

open access: yesJournal of Materials Research and Technology, 2023
The effect of cobalt on the precipitation hardening behavior of the maraging stainless steels was studied. The hardness test indicated that cobalt addition could advance peak aging time and generate a higher peak hardness. The statistical results of nano-

Precipitation hardening of an Al-4.2wt% Mg-0.6wt% Cu alloy [PDF]

open access: yes, 1998
The precipitation hardening of an experimental Al-4.2 wt% Mg-0.6 wt% Cu alloy has been studied. After a first initial jump, the yield strength increases almost linearly with the logarithm of the ageing time and a peak of hardness is reached after 11 days

Strain hardening rate in relation to microstructure in precipitation hardening materials [PDF]

open access: yes, 2000
The influence of microstructure on strain hardening is studied through Kocks-Mecking plots in a number of systems showing precipitation hardening : Al-Zn-Mg, Al-Mg-Si-Cu, and Fe-Cu. The presence of a supersaturated solid solution is shown to result in an

Hardening of an Al-Cu-Mg alloy containing type I and II S phase precipitates [PDF]

open access: yes, 2010
The effect of different thermo-mechanical treatments on the hardness of the 2024 (Al-Cu-Mg) alloy was studied. Artificial ageing was conducted through heating at a constant rate to specific temperatures followed by rapid cooling.

Exploring the improvement of strength and cryogenic impact toughness in hot-rolled high Mn austenitic steel for cryogenic application

open access: yesJournal of Materials Research and Technology, 2022
In general, there is a steep decrease in cryogenic (−196 °C) impact absorbed energy of high Mn austenitic steels after aging at 600–800 °C, which is also the temperature range of aging precipitation.

The thermodynamics of and strengthening due to co-clusters: general theory and application to the case of Al-Cu-Mg alloys [PDF]

open access: yes, 2009
Co-clusters in ternary or higher order metallic alloys are metastable structures involving two or more distinct alloying atoms that retain the structure of the host lattice. A thermodynamic model based on a single interaction energy of dissimilar nearest
