  Aging precipitation behavior and mechanical properties of Inconel superalloy aged at °C for up to h were investigated. The results showed that the precipitates of the aged alloy are M 23 C 6 and M 6 C carbides and γ′ phase. The carbide particles precipitated both at the grain boundaries and within grains, and the γ′ phase particles were situated at intragranular sites in Cited by:   G. Y. Lai and O. F. Kimball, “Aging Behavior of Alloy H and Associated Mechanical Property Changes,” General Atomic Report GA-A, November , General Atomic Company, San Diego, by: 7. Structural features, aging behavior, precipitation kinetics and mechanical properties of a Al–Mg–Si aluminum alloy subjected to equal channel angular pressing (ECAP) at different temperatures were comparatively investigated with that in conventional static aging by quantitative X-ray diffraction (XRD) measurements, differential scanning calorimetry (DSC) and tensile by: The effects of natural aging for a long period of time ( years) and as well as artificial aging on the mechanical properties and microstructure of multi-directionally forged (MDFed) aluminum alloys were systematically by:

To a large extent the mechanical properties and behavior of a metal depend on the dislocation content and structure, the size of the grains and the orientation or texture of the grains. The significant contribution to the high strength of heat-treatable aluminum alloys is due to the.

SKARET, Hans J. ROVEN2,3 1. School of Materials Science and Engineering, Jiangsu Province Key Laboratory of Materials Tribology. Structural features, aging behavior, precipitation kinetics and mechanical properties of a Al–Mg–Si aluminum alloy subjected to equal channel angular pressing (ECAP) at different.   Mechanical properties, microstructural events, residual stresses, and aging behavior of friction stir-welded AAT6 were investigated in this work. Microstructural and mechanical characterizations of the friction stir-welded joints in as-welded and post-welded conditions were made by means of optical metallography, transmission electron microscopy, X-ray diffraction for determination Cited by:

cold working prior to aging on the microstructure of the alloy. This research study, thus, aims (i) to characterize the aging response of the cold-drawn alloy with respect to hardness values of the alloy AEREX , and (ii) to determine the e ects of the cold work prior to aging on the stability of phases in this alloy. 2. Material and experimentAuthor: Hasan Ghiasi, Sirous Asgari. Aging behavior and related microstructural evolution of AZAg alloy as a function of aging temperature are systematically investigated. Results show that Ag addition can significantly enhance the age-hardening response of AZ80, improving its peak hardness and shortening the time to reach the peak by: Effect of aging temperature on precipitation behavior and mechanical properties of an AA alloy was examined. Long-term natural aging provides the best combination of strength and ductility by the precipitation of dense Guinier–Preston and Guinier–Preston–Bagaryatsky zones. This phenomenon, called “delayed hardening”, Cited by: 9. Vol. 36, No. 5 AGING BEHAVIOR % proof stress decreased with increasing the aging temperature, % proof stress of the alloy peak- aged at K was higher than that of the as-cast alloy. Hence, it is concluded that the peak-aging treatment is effective for increase in the tensile stress of this Mg-Li-Al-Cu by:
