development of Ti–V–Mo complex Microalloyed Hot-rolled 900-MPa-Grade High-Strength Steel

Acta Metallurgica Sinica(English Letters) 2015年第5期28卷 641-648页

作者： Ke Zhang Zhao-dong Li Xin-Jun Sun Qi-Long Yong Jun-Wei Yang Yuan-Mei Li Pei-Lin Zhao Department of Materials Science and Engineering Kunming University of Science and Technology Central Iron and Steel Research Institute Department of Materials Science and Engineering Huazhong University of Science and Technology R&D Center Laiwu Iron and Steel Group Co Ltd

A new Ti-V-Mo complex microalloyed hot-rolled high-strength steel sheet was developed by controlling a thermo-mechanical controlled processing （TMCP） schedule, in particular with variants in coiling temperature. The effects of coiling temperature （CT） on various hardening mechanisms and mechanical properties of Ti-V-Mo complex mi- croalloyed high-strength low-alloy steels were investigated. The results revealed that the steels are mainly strengthened by a combined effect of ferrite grain refinement hardening and precipitation hardening. The variation in simulated coiling temperature causes a significant difference in strength, which is mainly attributed to different precipitation hardening increment contributions. When the CT is 600 ℃, the experimental steel has the best mechanical properties： ultimate tensile strength （UTS） 1000 MPa, yield strength （YS） 955 MPa and elongation （EL） 17%. Moreover, about 82 wt% of the total precipitates are nano-sized carbide particles with diameter of 1-10 nm, which is randomly dispersed in the ferrite matrix. The nano-sized carbide particles led to a strong precipitation hardening increment up to 310 MPa.

A submicron photolysis polymer temporary bonding with ultra-fast laser de-bonding process of less than 20 s has been demonstrated where both photolysis polymer and polyimide are served as release layer and adhesive layer, respectively. In addition, the bonded structure provides high chemical resistance and mechanical strength for handling process. By measuring the electrical characteristics of devices before and after de-bond, it shows promising performance without degradation. Thus it can be a potential candidate for temporary bonding and de-bonding in 3d integration.

In the paper, a printed dipole with folded arms and U-shape structure for wireless cable modem is proposed. The printed dipole antenna is manufactured on a Fr4 substrate with a thickness of 0.6 mm, a permittivity of 4.4, and a loss tangent of 0.0245. The folded arms and U-shape structure can produce the bandwidth for WiFi applications. The simulated and measured results indicate the antenna has a bandwidth of 2.4-2.484 GHz. The measured antenna gain and efficiency of the antenna with metal board and plastic cover is good for applications. The design with small size and good antenna radiation is a good candidate for wireless cable modem.

Phase I of the OC6 project is focused on examining why offshore wind design tools underpredict the response (loads/motion) of the OC5-deepCwind semisubmersible at its surge and pitch natural frequencies. Previous investigations showed that the underprediction was primarily related to nonlinear hydrodynamic loading, so two new validation campaigns were performed to separately examine the different hydrodynamic load components. In this paper, we validate a variety of tools against this new test data, focusing on the ability to accurately model the low-frequency loads on a semisubmersible floater when held fixed under wave excitation and when forced to oscillate in the surge direction. However, it is observed that models providing better load predictions in these two scenarios do not necessarily produce a more accurate motion response in a moored configuration.

A cardinal feature of persistent pain that follows injury is a general suppression of behaviour, in which motivation is inhibited in a way that promotes energy conservation and recuperation. Across species, the anterior cingulate cortex is associated with the motivational aspects of phasic pain, but whether it mediates motivational functions in persistent pain is less clear. Using burrowing behaviour as an marker of non-specific motivated behaviour in rodents, we studied the suppression of burrowing following painful confirmatory factor analysis or control injection into the right knee joint of 30 rats (14 with pain) and examined associated neural connectivity with ultra-high-field resting state functional magnetic resonance imaging. We found that connectivity between anterior cingulate cortex and subcortical structures including hypothalamic/preoptic nuclei and the bed nucleus of the stria terminalis correlated with the reduction in burrowing behaviour observed following the pain manipulation. In summary, the findings implicate anterior cingulate cortex connectivity as a correlate of the motivational aspect of persistent pain in rodents.

A radar sensor for high speed moving objects is implemented using single chip CMOS UWB IC. To reduce the measuring and processing time for the fast moving target, the reliable and low power consumed envelope detection architecture is used at the expense of high resolution. The equivalent time sampling technique is adopted for UWB transceiver, employing delay locked loop and digitally synthesized impulse generator with 1 ns resolution to detect the fast moving target. The measured results with 4 × 1 micro-strip patch array antennas show that the detection range is from 1 m up to 4 m and the resolution is 15 cm. The scan time over 15 m distance is expected to be less than 150 μs.
