Influence of Aging Conditions on Fatigue Fracture Behaviour of 6063 Aluminum Alloy

Sultan Qaboos University Journal for Science, 2001
Aluminum - Magnesium - Silicon (Al-Mg-Si) 6063 alloy was heat-treated using under aged, peak aged and overage temperatures. The numbers of cycles required to cause the fatigue fracture, at constant stress, was considered as criteria for the fatigue ...

Precipitation hardening in dilute Al–Zr alloys

Journal of Materials Research and Technology, 2018
The aim of this study was to investigate the effect of solute content (hipoperitectic Al–0.22 wt.%Zr and hiperperitectic Al–0.32 wt.%Zr) on the precipitation hardening and microstructural evolution of dilute Al–Zr alloys isothermally aged.

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

Journal 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-

Particle distance distributions and their effect on precipitation strengthening [PDF]

Computer Methods in Materials Science, 2011
In this work, a general formulation of particle distances in glide planes is derived for arbitrary size distributions. The approach is designed to use the results of Wagner-Kampmann-type models.

Quantification of Precipitation Hardening and Evolution of Precipitates

MATERIALS TRANSACTIONS, 2002
Quantification of precipitation hardening is a challenging subject as it demands combined knowledge of precipitation strengthening mechanism and precipitate growth/coarsening kinetics. Having not seen many attempts on developing new theories in recent years, the authors are aware of the fact that many existing concepts and developed theories are ...
