Carbide precipitation and microstructure refinement of Cr-Co-Mo-Ni bearing steel during hot deformation

引用

Journal of Central South University 2015年第9期22卷 3265-3274页

作者：袁晓虹郑善举杨卯生赵昆渝 Faculty of Material Science and Engineering Kunming University of Science and Technology Central Iron and Steel Research Institute New Metallurgy Hi-tech Group Co. Ltd. China Iron and Steel Research Institute Group

The dynamic recrystallization and carbides precipitation of the Cr-Co-Mo-Ni bearing steel were investigated by hot compression tests performed at temperatures ranging from 850 ℃to 1080 ℃ with strain rate of 1-20 s-1. The activation energy（Q） for the tested steel is calculated to be around 682.99 k J/mol at a deformation strain of 0.6. Microstructural analysis by SEM shows that the dynamic recrystallization（DRX） behavior is dependent sensitively on the deformation strain, temperature and strain rate, while an exponential relationship between DRX grain size and Z parameter is obtained from the computational formula. Moreover, the M6C-type carbides（〈1 μm） act as the main prohibitor of grain coarsening, and the polynomial regression relationship between them is worked out. With electron backscatter diffraction（EBSD） observation, DRX is the main nucleation mechanism responsible for the formation of new grains during hot compression. In conclusion, the interaction between DRX affected by hot deformation parameters and carbides precipitation determines the ultimate grain size refinement.

The structure and working principle of a kind of permanent-magnet adsorption tracked wall-climbing ro-bot used in ship was analyzed in this paper. The robot can complete vertical climbing wall function when perma-nent-magnet adsorption tracked was driven by ac servo motor. In order to improve the load capacity and obstaclesurmounting ability of robot, a new permanent-magnet auxiliary caster adsorption mechanism and driven wheelfloating mechanism were used for the design of structure. In thispaper, the mechanical state of the permanent-mag-netic adsorption tracked climbing mechanism was analyzed. Through the magnetic simulation and experimental a-nalysis of magnetic adsorption system, the adsorption unit structure and electric drive system parameters of thepermanent-magnet tracked wall-climbing robot were reasonably designed.

This paper proposes a method to design an Electronic Hand Glove which would help deaf and blind people to communicate easily. There are around 285 million visually impaired people in the world and 900,000 deaf and mutes. They use sign language to communicate with others. But it's very difficult to use and understand this sign language as it contains approximately 6000 gestures. The model uses 26 gestures of hand to communicate alphabets and 10 more gestures to communicate numbers. This would help the deaf person to communicate with others by typing text on LCD screen through hand gestures. The text is converted into speech so that the blind person could hear and communicate.

作者： Li, Yan-Feng Mi, Jinhua Liu, Y.U. Yang, Yuan-Jian Huang, Hong-Zhong Institute of Reliability Engineering University of Electronic Science and Technology of China No. 2006 Xiyuan Avenue West Hi-Tech Zone Chengdu Sichuan611731 China

In the calculation of dynamic fault trees, the existing state space-based methods, such as Markov chain method, are basically global-state models, which make the solution procedure very complex. Bayesian networks have become a popular tool to build probability models and conduct inference for reliability design and analysis in various industry fields. The "Üstate explosion" problem can be alleviated by Bayesian networks. Furthermore, to obtain sufficient failure data sets in real engineering systems is extremely difficult and thus causes the parametric uncertainty in failure data. To address these issues, a novel dynamic fault tree analysis method based on the continuous-time Bayesian networks under fuzzy numbers is proposed in this article. The probability distributions under fuzzy numbers for the output variable of dynamic logic gates are determined. The calculation of fuzzy failure probability of a system is presented. Finally, an example is given to demonstrate the effectiveness of the proposed method. © 2015 Institution of Mechanical Engineers.

As many malicious apps have been distributed in Android markets, it is urgent to fix the vulnerabilities exploited by these apps and develop effective mitigation methods. In this paper, we identify a common vulnerability in many Android apps. This vulnerability is rooted in an unprotected Android component, called "Activity". Utilizing this vulnerability, a malicious app can stealthily and cannily collect sensitive user data. To better understand this issue, we have built "Activityhijacker", an app that can detect the right moment to hijack the Activity component and intercept a user's password while it is being inputted in real time. To assess the prevalence of this vulnerability, we further analyzed 8 Android OSs (version 2.x to 5.x) and 22 banking apps collected in January 2016 from various Android markets. Our results show that all these Android OSs and apps are susceptible to the vulnerability; 14 out of 22 banking apps can be hijacked without any prompts. We further present a mitigation mechanism that restricts the Activity component to authorized apps.
