| 1 | Warm Deformation of Low Carbon Steel Using Forward Extrusion-Equal Channel Angular Pressing Technique显示文摘A combination of extrusion and equal channel angular pressing (ECAP) was used to deform a plain low carbon steel. This process consists of two successive deformations by extrusion and ECAP in a single die (Ex-ECAP). Cylindrical samples were heated to predefined temperatures (650 and 850 ℃) and then pressed through a die channel with crosshead speed of 10 mm/s. Microstructure and resultant mechanical properties of processed material were studied. The results showed that pressing temperature has a significant effect on the resultant microstructure. While at 650 ℃, the cold worked structure with elongated ferrite grains were obtained, and at 850 ℃ the microstructure consisted of elongated ferrite grains and very fine grains at their boundaries as a consequence of continuous dynamic recrystallization (CDRX) of ferrite phase. Also at 850 ℃, a particular microstructure consisted of cold worked ferrite and static recrystallized grains on shear bands was obtained. | B Eghbali M Shaban | 2013 | Journal of Iron and Steel Research(International)2013，20，2： | 9 |
| 2 | Comparative performance of different urea coating materials for slow release显示文摘Approximately 70%of the applied urea fertilizer may be lost into the environment.This loss is due to leaching,decomposition and ammonium volatilization in soil,water and air.Through coating,the slow release technology can be used to reduce losses and to increase the fertilizer efficiency.Sulfur has been used as a coating material,but the coating cracks easily because of its friability,sometimes being peeled off from the urea surface.In this study,four types of materials,namely,gypsum,cement,sulfur and zeolite,were mixed and used as coating materials to search for the most effective and cheap coating materials.The primary reasons for selecting these materials were improving fruit quality and preventing plant diseases,providing a plant nutrient,increasing soil fertility and water retention.The materials were also selected based on their availability,processiblity and price.The effects of the coating materials,thickness,drying time,sieving and sealant on the crushing strength and dissolution rate of urea were investigated.Coated urea with the same proportion of gypsum-sulfur exhibited high crushing strength and lower dissolution rate.However,the performance was further enhanced by applying molten paraffin wax on the hot urea surface.SEM images demonstrated that the micro-structure of gypsum-sulfur coated urea after sieving resulted in a smoother coated layer.The efficiency of the coated urea was improved by26%using gypsum-sulfur(20%total coating),3%paraffin wax and sieving the coating materials before application. | Khairul Ridzwan Mohd Ibrahim Farahnaz Eghbali Babadi Robiah Yunus | 2014 | Particuology2014，12，6： | 6 |

| 4 | 搅拌铸造法制备AA2024−TiO2纳米复合材料显示文摘考虑到在非原位铸造法制备复合材料时不使用TiO2纳米颗粒作为AA2024合金的增强相,采用搅拌铸造法制备AA2024−x%TiO2(np)(x=0,0.5%,1%,体积分数)纳米复合材料。利用光学显微镜和扫描电子显微镜研究样品的结构性能,并采用硬度和拉伸试验研究其力学性能。结果表明,添加1%TiO2(体积分数)纳米颗粒后,样品的晶粒尺寸和枝晶臂间距分别减小约66%和31%;硬度、抗拉强度、屈服强度和伸长率分别提高约25%、28%、4%和163%。在拉伸试样的断口表面观察到团聚在基体中的纳米颗粒。纳米复合材料结构中纳米颗粒的团聚是其强度在强化机制下减弱的因素。 | Mehrdad SHAYAN Beitallah EGHBALI Behzad NIROUMAND | 2020 | Transactions of Nonferrous Metals Society of China2020，30，11： | 6 |
| 5 | Microstructure and mechanical properties of SiC-particle-strengthening tri-metal Al/Cu/Ni composite produced by accumulative roll bonding process显示文摘In this study, a multilayer Al/Ni/Cu composite reinforced with Si C particles was produced using an accumulative roll bonding(ARB) process with different cycles. The microstructure and mechanical properties of this composite were investigated using optical and scanning microscopy and hardness and tensile testing. The results show that by increasing the applied strain, the Al/Ni/Cu multilayer composite converted from layer features to near a particle-strengthening characteristic. After the fifth ARB cycle, a composite with a uniform distribution of reinforcements(Cu, Ni, and SiC) was fabricated. The tensile strength of the composite increased from the initial sandwich structure to the first ARB cycle and then decreased from the first to the third ARB cycle. Upon reaching five ARB cycles, the tensile strength of the composite increased again. The variation in the elongation of the composite exhibited a tendency similar to that of its tensile strength. It is observed that with increasing strain, the microhardness values of the Al, Cu, and Ni layers increased, and that the dominant fracture mechanisms of Al and Cu were dimple formation and ductile fracture. In contrast, brittle fracture in specific plains was the main characteristic of Ni fractures. | Moslem Tayyebi Beitallah Eghbali | 2018 | International Journal of Minerals,Metallurgy and Materials2018，25，3： | 5 |
| 6 | Fabrication and characterization of GNPs and CNTs reinforced Al7075 matrix composites through the stir casting process显示文摘This study investigated the effects of adding graphene nanoplates(GNPs)and carbon nanotubes(CNTs)into the Al7075 matrix via the stir casting method on the microstructure and mechanical properties of the fabricated composites.By increasing the volume fraction of rein-forcements,the fraction of porosity increased.The X-ray diffraction results showed that the addition of reinforcements into the Al7075 changed the dominant crystal orientation from(002)to(111).Field emission scanning electron microscopy images also showed the distribution of clustered reinforcements in the matrix.Between the two reinforcements,the addition of CNTs generated a lower fraction of porosities.Through the addition of 0.52vol%GNPs into the matrix,the hardness,ultimate tensile strength and uniform elongation increased by 44%,32%,and 180%,respectively.Meanwhile,the presence of 0.71vol%CNTs in the matrix increased the hardness,tensile strength and uniform elongation by 108%,129%,and 260%,respectively. | Siavash Imanian Ghazanlou Beitallah Eghbali | 2021 | International Journal of Minerals,Metallurgy and Materials2021，28，7： | 4 |
| 7 | EBSD表征变形后退火Al7075/石墨烯纳米片/碳纳米管复合材料显示文摘研究变形后退火对碳纳米管(CNTs)和石墨烯纳米片(GNPs)增强热轧Al7075基复合材料显微组织演变的影响。对搅拌铸造样品进行多道次热轧,然后在450℃下退火4 h。采用SEM、EDS和EBSD技术观察材料的显微组织演变。EBSD数据显示,添加体积分数(下同)为0.87%的GNPs和CNTs可明显抑制再结晶的发生。当添加0.96%的CNTs时,再结晶受到部分抑制。而当添加0.92%的GNPs时,明显加快了粒子激发形核(PSN)机制导致的再结晶。在有增强相存在的情况下,再结晶晶粒的体积分数与PSN的产生有显著的关系。主要织构的强度和类型都取决于增强相的种类。 | Siavash IMANIAN GHAZANLOU Baitallah EGHBALI Roumen PETROV | 2021 | Transactions of Nonferrous Metals Society of China2021，31，8： | 4 |

| 9 | Strain hardening behavior, strain rate sensitivity and hot deformation maps of AISI 321 austenitic stainless steel显示文摘Hot compression tests were performed on AISI 321 austenitic stainless steel in the deformation temperature range of 800–1200℃ and constant strain rates of 0.001,0.01,0.1,and 1 s^(−1).Hot flow curves were used to determine the strain hardening exponent and the strain rate sensitivity exponent,and to construct the processing maps.Variations of the strain hardening exponent with strain were used to predict the microstructural evolutions during the hot deformation.Four variations were distinguished reflecting the different microstructural changes.Based on the analysis of the strain hardening exponent versus strain curves,the microstructural evolutions were dynamic recovery,single and multiple peak dynamic recrystallization,and interactions between dynamic recrystallization and precipitation.The strain rate sensitivity variations at an applied strain of 0.8 and strain rate of 0.1 s^(−1) were compared with the microstructural evolutions.The results demonstrate the existence of a reliable correlation between the strain rate sensitivity values and evolved microstructures.Additionally,the power dissipation map at the applied strain of 0.8 was compared with the resultant microstructures at predetermined deformation conditions.The microstructural evolutions strongly correlated to the power dissipation ratio,and dynamic recrystallization occurred completely at lower power dissipation ratios. | Mehdi Shaban Ghazani Beitallah Eghbali | 2021 | International Journal of Minerals,Metallurgy and Materials2021，28，11： | 2 |

| 14 | Grain Refinement in a Low Carbon Steel Through Multidirectional Forging显示文摘Grain refinement is one of the successful and low-cost methods to develop metals having excellent combination of strength and ductility. Low carbon steel was deformed by using multidirectional forging (MDF) technique at room temperature. The influence of strain amount and annealing process on the microstructure and mechanical properties of investigated steel was studied. The grain refinement mechanism was studied by the microstructure observation. The results showed that the grain refinement was attained by multidirectional forging technique. The initial coarser grains of average 38 μm size fragmented into very fine ferrite with grain sizes of about 1.2 μm. After MDF, the strength properties improved significantly, although uniform elongation and elongation decreased with increasing strain. | V Soleymani B Eghbali | 2012 | Journal of Iron and Steel Research(International)2012，19，10： | 1 |
