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.

Precipitation hardening in gold-cobalt alloys. [PDF]
The Bulletin of Tokyo Medical and Dental University, 1976 The precipitation hardening in gold-cobalt alloys containing less than 5 wt.%Co was studied by means of resistivity, hardness, X-ray diffraction, and optical microscopic examination. The hardness curves showed two hardness peaks after isothermal ageing below the temperature of 250 or 300 degrees C.

AbstractModels for precipitation hardening (PH) at room temperature have been available for a long time. In spite of the importance of PH, it took a long time to establish models for elevated temperatures. In fact, empirically the room temperature models have also been used at higher temperatures.

Casting of precipitation-hardening steel
, 2014 17-4 PH and its cast equivalent Cb7Cu-1 are stainless precipitation-hardening steels with high strength and good corrosion resistance. Literature shows that the material properties can be tailored in detail by fine-tuning alloy composition and heat treatment. However, the result is also very sensitive to small changes in production environment.

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 ...
