. Results show that the fatigue life(Nf) of DD10 alloy exhibits different temperature dependence under various strain ranges. Under low strain range, the alloy exhibits a longer Nfat 760 °C than that at980......
concentration has a great influence on the volume fraction, the morphology and the size of second phase. The Mg–1.95Zn–0.75Ca(wt%) alloy with the highest volume fraction, continuous network and largest size of Ca2Mg6Zn3 phase showed the lowest elongation to failure of about 7%, while the Mg–0.73Zn–0.12Ca(wt%) alloy with the lowest volume fraction and smallest size of Ca2Mg6Zn3 phase showed the highest......
. School of Mechanical Engineering and Automation, Beihang University2. Avic Chengdu Aircraft Industrial (Group) Co. Ltd摘 要:2A12 aluminum alloy powders were... obtained at HIPing temperatures of 490 and 580 ℃. The low ductility exhibited by the P/M aluminum alloy HIPed at different temperatures was believed to arise from a combination of the existence......
fillers are used to minimize the carbon migration,but the results are not truly adequate.In this paper,Ni–Fe alloy(chromium-free) has been used as the intermediate buffer layer in the weld buttering deposit to address the issue of carbon migration and subsequent metallurgical deterioration.The weld pads with and without buffer layers of Ni–Fe alloy have been investigated and compared in detail......
with the increase in strain. Stress instability phenomenon of PM Ti2AlNb alloys was more obvious than that of wrought alloy. Flow stress fluctuation at the initial stage of deformation is related... and optimized rolling parameters. Tensile properties of PM Ti2AlNb alloy were improved, and the porosity was reduced after ring rolling.关键词:......
is also influenced by cyclic plastic deformation mechanisms of the alloy with crystal orientations, and the [001] specimens are plastically deformed by wave slip mechanism and fracture along the non... and analyze the cyclic plastic deformation for the alloy with different orientations.关键词:......
welded of aluminum alloy 6063-T5. Good correlations between the input variables, i.e., welding parameters and physical properties of the materials, and the welding heat inputs obtained... conductivities of the welded alloys affected the welding heat input significantly. Mechanical properties, including hardness and tensile properties, of friction-stir-welded aluminum alloy 6063 were in good......
–Mg alloys was first ascertained to be derived from the growth mechanism of the precipitates at the grain boundary(GB). Moreover, a small number of GB precipitates can be obtained in the aged alloy... sensitivity in alloy with a high Cu/Li mass ratio.关键词:......
Sieverts apparatus. The alloy electrodes were charged and discharged with a constant current density in order to investigate the electrochemical hydrogen storage kinetics of the alloys. The results... alloy, however, a certain amount of amorphous phase is clearly found in the as-quenched alloys substituted by Co. Furthermore, both the rapid quenching and the Co substitution significantly improve......
