| 1 | 等径角挤压晶粒细化技术对纯铝显微组织演变、力学性能和腐蚀行为的影响(英文)显示文摘在室温下,采用等径角挤压法加工纯铝样品10道次。研究等径角挤压道次数对加工样品显微组织演变、力学性能、变形均匀性和腐蚀行为的影响。所施加的应变导致晶粒尺寸明显减小,等径角挤压前,晶粒尺寸为390μm,经等径角挤压2、4和10道次后,晶粒尺寸分别减小至1.8、0.4和0.3μm。随着等径角挤压道次数的增加,显微硬度、变形均匀性和拉伸强度增大,而伸长率下降。浸泡试验、开路电势、Tafel极化、循环极化和恒电位测试表明,与铸态样品相比,在3.5%Na Cl溶液中,经等径角挤压样品的耐蚀性明显提高。增加挤压道次数能成功用来生产具有高错位角、高力学性能和耐蚀性的超细晶大块纯铝。 | Mohamed Ibrahim ABD EL AAL M.M.SADAWY | 2015 | Transactions of Nonferrous Metals Society of China2015，25，12： | 6 |
| 2 | 纯铝等径角挤压及等径角挤压和直接挤压结合的塑性变形3D有限元模拟和实验验证(英文)显示文摘对纯铝进行等径角挤压、等径角挤压结合不同挤压比直接挤压及直接挤压,并采用刚-粘塑性3D有限元模拟进行分析。利用3D有限元模拟研究不同成形过程变形Al-1080的载荷-位移行为、塑性变形特征和有效塑性应变均匀性。用显微组织观察、显微硬度分布图、有效塑性应变和显微硬度值验证模拟结果。结果表明:模拟结果与实验结果一致;模拟载荷-位移曲线和最大载荷与实验结果接近;显微硬度分布图符合有效塑性应变等高线,证实了3D有限元模拟结果。等径角挤压工件的变形均匀性程度比其他变形过程的高。根据平均有效塑性应变计算了显微硬度值。预测显微硬度值与实验结果吻合。横向和纵向显微组织观察验证了不同成形过程中3D有限元模拟有效塑性应变和显微硬度分布结果。 | Mohamed Ibrahim Abd EL AAL | 2017 | Transactions of Nonferrous Metals Society of China2017，27，6： | 5 |
| 3 | Improvement of geotechnical properties of sabkha soil utilizing cement kiln dust显示文摘Improvement of properties of weak soils in terms of strength,durability and cost is the key from engineering point of view.The weak soils could be stabilized using mechanical and/or chemical methods.Agents added during chemical stabilization could improve the engineering properties of treated soils.Stabilizers utilized have to satisfy noticeable performance,durability,low price,and can be easily implemented.Since cement kiln dust(CKD) is industrial by-product,it would be a noble task if this waste material could be utilized for stabilization of sabkha soil.This study investigates the feasibility of utilizing CKD for improving the properties of sabkha soil.Soil samples are prepared with 2% cement and 10%,20% or 30% CKD and are tested to determine their unconfined compressive strength(UCS),soaked California bearing ratio(CBR) and durability.Mechanism of stabilization is studied utilizing advanced techniques,such as the scanning electron microscope(SEM),energy dispersive X-ray analysis(EDX),backscattered electron image(BEI) and X-ray diffraction analysis(XRD).It is noted that the sabkha soil mixed with 2% cement and 30% CKD could be used as a sub-base material in rigid pavements.The incorporation of CKD leads to technical and economic benefits. | Abdullah A.Al-Homidy Mohammed H.Dahim Ahmed K.Abd El Aal | 2017 | Journal of Rock Mechanics and Geotechnical Engineering2017，9，4： | 3 |

| 17 | Gamma induced changes in Makrofol/CdSe nanocomposite films显示文摘We applied an ex-situ casting procedure to prepare a nanocomposite(NCP)from Makrofol polycarbonate(PC)and CdSe nanoparticles.The CdSe nanoparticles were prepared by a thermolysis procedure in the presence of N_(2) gas flow.Rietveld refinement of x-ray data illustrated that the CdSe adopts a cubic zinc blend structure of 6.057 A lattice parameter and 2 nm typical grain size.Samples from the prepared NCP were exposed to γ dosages(20 kGy-250 kGy).The modifications induced in the NCP films owing to γ dosages have been studied.Theγirradiation(50 kGy-250 kGy)causes crosslinks that reduce the optical bandgap from 4.15 eV to 3.81 eV,associated with an increase in dielectric parameters and refractive index.This is attributed to an increase in the mass fraction of the disordered regions as specified by x-ray diffraction.The PC-CdSe NCP was found to have a reaction to color modification which makes it suitable for saleable reproduction on a printing press. | Ali A.Alhazime M.ME.Barakat Radiyah A.Bahareth E.M.Mahrous Saad Aldawood S.Abd El Aal S.A.Nouh | 2022 | Chinese Physics B2022，31，9： | 1 |
