| 1 | Intergranular corrosion behavior and mechanism of the stabilized ultra-pure 430LX ferritic stainless steel显示文摘Intergranular corrosion(IGC) behavior of the stabilized ultra-pure 430 LX ferritic stainless steel(FSS) was investigated by using double loop electrochemical potentiokinetic reactivation(DL-EPR) and oxalic acid etch tests to measure the susceptibility of specimens given a two-step heat treatment. The results reveal that IGC occurs in the specimens aged at the temperature range of 600–750℃ for a short time. The aging time that is required to cause IGC decreases with the increase of aging temperature. A longer aging treatment can reduce the susceptibility to IGC. The microstructural observation shows that M(23)C6 precipitates form along the grain boundaries, leading to the formation of Cr-depleted zones. The presence of Cr-depleted zones results in the susceptibility to IGC. However, the atoms of stabilizing elements replace chromium atoms to form MC precipitates after long-time aging treatment, resulting in the chromium replenishment of Cr-depleted zones and the reduction of the susceptibility to IGC. | Peize Cheng Ning Zhong Nianwei Dai Xuan Wu Jin Li Yiming Jiang | 2019 | Journal of Materials Science & Technology2019，35，8： | 5 |
| 2 | In-building coverage of millimeter-wave wireless networks from channel measurement and modeling perspectives显示文摘To progress cost-effective deployment of millimeter-wave(mm Wave)wireless networks for indoor users,the prediction of indoor-to-indoor(I2I)and outdoor-to-indoor(O2I)coverage based on field measurement studies is of great interest to the future generation mobile communication system.First,measurements in I2I and O2I scenarios,which have advantages in terms of achieving a fair comparison of channel characteristics across different mm Wave bands and bandwidths,are performed.Next,the developed dual-slope path loss model with a break-point distance is found to well fit omnidirectional and directional measured I2I data,especially at 39.5 GHz,revealing that the transition from lit or shadow regions to totally blocked regions is abrupt.Combined with space-time propagation characteristics,the indoor blockage effect on path loss and angular spread is investigated,therein being essential for the design of beam-steering and tracking algorithms.Double-directional measurement results show that most dominant paths arrive along the line-ofsight path,and only a few in-building reflections can be detected in higher frequency bands.Based on the joint analysis of channel measurement and modeling results,several mm Wave network design and in-building coverage enhancement insights are presented. | Peize ZHANG Cheng YI Bensheng YANG Cheng-Xiang WANG Haiming WANG Xiaohu YOU | 2020 | Science China(Information Sciences)2020，63，8： | 2 |
