Modelling of Precipitation Hardening Behavior of 17-4PH Steel and The Influence of Previous Deformation [PDF]

open access: yesMaterials Research
UNS S17400 (AISI 17-4PH) is a precipitation hardening steel with several applications in energy generation, oil and gas, aerospace and chemical industries. The hardening effect is mainly produced by the precipitation of copper rich phases (CRP).

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

open access: yesSultan 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 ...

Solute effects on edge dislocation pinning in complex alpha-Fe alloys [PDF]

open access: yes, 2017
Reactor pressure vessel steels are well-known to harden and embrittle under neutron irradiation, mainly because of the formation of obstacles to the motion of dislocations, in particular, precipitates and clusters composed of Cu, Ni, Mn, Si and P.

Precipitation hardening in dilute Al–Zr alloys

open access: yesJournal 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

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-
