| 1 | 新型SPD工艺对AM60镁合金性能不均匀性的影响显示文摘利用新型大塑性变形(SPD)技术提高镁合金的冶金性能。在此过程中,先进行循环挤压−压缩−角挤压(CECAP)过程,再在出口处进行挤压,起到附加背压的作用。因此,与等径角挤压(ECAP)相比,期望获得更加均匀和优异的力学性能。为了评价这种新方法的有效性和能力,对AM60镁合金进行加工。有限元分析表明,新方法的应变值和均匀应变分布均显著提高。此外,与传统的ECAP相比,新方法的压应力增加约110%。实验结果表明,经新工艺处理后,试样的硬度和强度均有显著提高,这是由于其晶粒细化,显微组织更加均匀,并且细化的β相沿晶界均匀分布。因此,该新工艺在未来镁合金生产中具有广阔的应用前景。 | Siroos AHMADI Vali ALIMIRZALOO Ghader FARAJI Ali DONIAVI | 2021 | Transactions of Nonferrous Metals Society of China2021，31，3： | 8 |

| 6 | A comparative study of stress influence on fracture apertures in fragmented rocks显示文摘This study compares the calculated fracture apertures in a fragmented rock layer under different stress scenarios using two different approaches. Approach 1 is a simplified method using a two-dimensional(2 D) mapping of the fracture network and projects the far-field stresses to individual fractures, and calculates the dilation, normal and shear displacements using experimental stiffnesses available in the literature. Approach 2 employs a three-dimensional(3 D) finite element method(FEM) for the mechanical analysis of the fragmented rock layer considering the interaction with the neighbouring rock layers, frictional interfaces between the rock blocks, stress variations within the fragmented rock layer,and displacements, rotations and deformations of rock blocks. After calculating the fracture apertures using either of the approaches, the permeability of the fragmented rock layer is calculated by running flow simulations using the updated fracture apertures. The comparison between the results demonstrates an example of the inaccuracies that may exist in methods that use simplified assumptions such as2 D modelling, ignoring the block rotations and displacements, projected far-field stresses on fractures,and the stress variations within the rock layer. It is found that for the cases considered here, the permeability results based on apertures obtained from the simplified approach could be 40 times different from the results from apertures calculated using a full mechanical approach. Hence, 3 D mechanical modelling implementing realistic boundary conditions, while considering the displacements and rotations of rock blocks, is suggested for the calculation of apertures in fragmented rocks. | Hossein Agheshlui Mohammad H.Sedaghat Siroos Azizmohammadi | 2019 | Journal of Rock Mechanics and Geotechnical Engineering2019，11，1： | 1 |

| 10 | 湖南古丈奥陶纪红石林地层特征与石灰岩沉积环境分析显示文摘湘西古丈红石林国家地质公园出露着奥陶系牯牛潭组红色石灰岩地层,含角石化石,被认为是海相红层。野外观察地层红色深浅与其层理/层次变化关系判断为近于同期形成,属原生色。水生化石存在红层中,前者反映水下缺氧条件,而红层指示着氧化环境,两种指示尖锐对立,意味着可能至少一方存在认识偏差。采样分析结果表明,赤铁矿和针铁矿是其中可以被检测到的磁性矿物;地层碳酸钙含量介于20%—24%,粒度以粉砂为主显示双峰与风积物高度相似而与海相红层差别大;因此,红石林地层可能不是海相化学沉积,而是强氧化条件下形成的以粉砂为主的红色钙质胶结碎屑沉积物。红石林地层稀土元素标准配分模式与风积物类似,与海相红层差别甚大;红层中存在同一层位红色和灰色共存的网纹构造,指示着同期氧化与还原条件共存状态;红层中发育着网纹状瘤状钙结核既顺层也垂直层面同时发展,这些现象在海相环境均难以形成,似乎只有地表成土环境才能得以发生。表明红石林地层可能是风积物为物源,在地表成土过程形成的沉积序列。红石林沉积环境可能与澳洲干旱区现代临时性湖积碳酸盐环境较为接近:短暂积水不仅留下动物脚印、海相化石和泥裂,同时将半干旱条件下碳酸盐胶结粉砂沉积物变成现代泥灰岩-石灰岩,实质上是钙质胶结粉砂岩,在地表氧化成为红色。因此,古丈红石林地层可能是一套记录着奥陶纪地球冷暖变化的海陆边缘相风积粉砂粒级为主的钙质胶结碎屑沉积物地层。 | 刘秀铭 吉金平 章涛 陈家胜 Ali Rashid Tabrez Siroos Jafari | 2021 | 地球环境学报2021，12，1： | 1 |
