| 1 | Processing of AM60 magnesium alloy by hydrostatic cyclic expansion extrusion at elevated temperature as a new severe plastic deformation method显示文摘Hydrostatic cyclic expansion extrusion(HCEE) process at elevated temperatures is proposed as a method for processing less deformable materials such as magnesium and for producing long ultrafine-grained rods. In the HCEE process at elevated temperatures, high-pressure molten linear low-density polyethylene(LLDPE) was used as a fluid to eliminate frictional forces. To study the capability of the process,AM60 magnesium rods were processed and the properties were investigated. The mechanical properties were found to improve significantly after the HCEE process. The yield and ultimate strengths increased from initial values of 138 and 221 MPa to 212 and 317 MPa, respectively.Moreover, the elongation was enhanced due to the refined grains and the existence of high hydrostatic pressure. Furthermore, the microhardness was increased from HV 55.0 to HV 72.5. The microstructural analysis revealed that ultrafine-grained structure could be produced by the HCEE process. Moreover, the size of the particles decreased, and these particles thoroughly scattered between the grains. Finite element analysis showed that the HCEE was independent of the length of the sample, which makes the process suitable for industrial applications. | Farshad Samadpour Ghader Faraji Armin Siahsarani | 2020 | International Journal of Minerals,Metallurgy and Materials2020，27，5： | 4 |

| 14 | Investigation of the stability and hydrodynamics of Tetrosomus gibbosus carapace in different pitchangles显示文摘In this paper,stability properties of Tetrosomus gibbosus have been experimentally and numerically studied in pitching movements.This fish lives in southern offshores of Iran.Boxfishes usually live in extremely turbulent parts of seas and oceans,with high stability and maneuverability that has caught the attention of scientists.Their body shape let them swim with a quite rapid speed.Studies on Boxfishes have had influences on automotive and marine industries.The CAD file of the boxfish was created using optical CMM.Also a model was built and tested in a subsonic wind tunnel and a numerical study was conducted in virtual wind tunnel.The experimental results are consistent with the numerical ones and also support the findings of other studies on similar boxfishes.These results show that the flow around the fish,which is a consequence of its body shape,tries to maintain the stable position of the fish by resisting against the external force tilting the fish from its stable horizontal posture.The ventral and dorsal keels of the boxfish generate column-like vortices in horizontal direction which play an imperative role in maintaining the stability of the fish. | Mahyar Malekidelarestaqi Alireza Riasi Hadi Moradi Mohammad Samadpour | 2019 | Journal of Hydrodynamics2019，31，2： | 0 |
| 15 | Simply synthesized TiO_2 nanorods as an effective scattering layer for quantum dot sensitized solar cells显示文摘TiO2nanorod layers are synthesized by simple chemical oxidation of Ti substrates. Diffuse reflectance spectroscopy measurements show effective light scattering properties originating from nanorods with length scales on the order of one micron. The films are sensitized with CdSe quantum dots(QDs) by successive ionic layer adsorption and reaction(SILAR)and integrated as a photoanode in quantum dot sensitized solar cells(QDSCs). Incorporating nanorods in photoanode structures provided 4- to 8-fold enhancement in light scattering, which leads to a high power conversion efficiency, 3.03%(Voc = 497 mV, Jsc = 11.32 mA/cm2, FF = 0.54), in optimized structures. High efficiency can be obtained just by tuning the photoanode structure without further treatments, which will make this system a promising nanostructure for efficient quantum dot sensitized solar cells. | Mahmoud Samadpour Azam Iraji zad Mehdi Molaei | 2014 | Chinese Physics B2014，23，4： | 0 |
