The Effect Of Cooling Rate On Cyclic Stress Strain Response Of Al-2024
نویسنده
چکیده
Cyclic stress strain curves (CSSC) response of Al-2024 Annealed condition was conducted under symmetric tension-compression at room temperature and constant frequency, using a servo-hydraulic testing machine, to study the effect of cooling rate on cyclic stress strain curves (CSSC) response. The fatigue response of Al-2024 alloy was evaluated macroscopically in terms of cyclic stress strain response and microscopically in terms of appearance of precipitations free zones. It was found that the cyclic stress strain response of air-cooled specimens group exhibited a higher saturation stress with plastic strain and smaller PFZ regions whereas the cyclic stress strain response of furnace cooled specimens group exhibited a lower saturation stress and

Effect of Fe additive on plastic deformation for crush-boxes with closed-cell metal foams, Part I: Al-composite foam compression response
AbstractIn this paper, we investigate effect of Fe–intermetallic compounds on plastic deformation of closed-cell composite Aluminum Foam as filler of thin-walled tubes. However, deformation of the Aluminum foam-filled thin-walled tubes as crushed-box will be presented in Part (II). Composite foams of AlSi7SiC3 and AlSi7SiC3-(Fe) as closed cell were synthesized by powder metallurgy foaming metho...
متن کاملCyclic Behavior of Beams Based on the Chaboche Unified Viscoplastic Model
In this paper, ratcheting behavior of beams subjected to mechanical cyclic loads at elevated temperature, using the rate dependent Chaboche unified viscoplastic model with combined kinematic and isotropic hardening theory of plasticity, is investigated. A precise and general numerical scheme, using the incremental method of solution, is developed to obtain the cyclic inelastic creep and plastic...
متن کاملTheoretical study of the effect of internal strain on the bond length and rate of hydrolysis in cyclic amides
The internal strain in cyclic amides are explained as a factor of resonance that are effected on the bond length C-N and are a major factor of rates of hydrolysis. The cyclic amides in this study are optimized by Gaussian program and the bond length of C-N in the rings are studied by HF/6-31G*.
متن کاملThe Effect of Fe Additive on Plastic Deformation for Crush-Boxes with Closed-Cell Metal Foams, Part II: Al-Composite Foam-Filled brass tubes Compression Response
The brass tubes with foam cores of AlSi7SiC3, AlSi7SiC3Fe1 and AlSi7SiC3Fe3 were produced as the crush-boxes with circle and square cross-section. Then axial compressive behavior and energy absorption capability of the foam-filled tubes were investigated during the quasi-static progressive plastic buckling. The uniaxial compressive stress–strain curves of the foam-filled brass tubes exhibited t...
