Modeling of numerical simulation and experimental verification for carburizing-nitriding quenching process

中国有色金属学会会刊：英文版 2006年第B2期16卷 566-571页

作者： R. MUKAI T. MATSUMOTO JU Dong-ying T. SUZUKI h. saito Y. ITO high-Tech Research Center Special Researcher Saitama Institute of Technology Fukaya 369-0293 Japan Department of Mechanical Engineering Saitama Institute of Technology Fukaya 369-0293 Japan Research Center of high Technology Anshan University of Science and Technology Anshan 114044 China Department of Technology Development Tobuyakin Ltd. Japan

A model considering quantitative effects of diffused carbon and nitrogen gradients and kinetics of phase transformation is presented to examine metallo-thermo-mechanical behavior during carburized and nitrided quenching. Coupled simulation of diffusion, phase transformation and stress/strain provides the final distribution of carbon and nitrogen contents as well as residual stress and distortion. Effects of both transformation and lattice expansion induced by carbon and nitrogen absorption were introduced into calculating the evolution of the internal stress and strain. In order to verify the method and the results, the simulated distributions of carbon and nitrogen content and residual stress/strain of a ring model during carburized and nitrided quenching were compared with the measured data.

本文提出了一种用于地震射线层析成像的算法,地震射线层析成像中,速度分布图是根据旅行时间的测量来重建的.所用算法是迭代算法;此算法中,包含了说明射线弯曲度的旅行时间计算和用阻尼最小平方法作模型改进两部分.为了检验改进后的重建程序,需要进行一些数字试验.这些试验的结果表明,可以应用迭代算法来精确地重建速度分布剖面.最后,我们应用了地震射线层析成像技术作水坝和桥墩基岩方面的探测.我们得到了详细的速度分布图,根据这个速度分布图就能够识别断裂带或蚀变带.

本文描述的是一个干涉测量法,用来分别得出二维应力分布的两个主应力。根据透明弹性平板的应力-应变状态及其在马赫-塞恩达（Mach-Zehnder）干涉仪上所观察到的光强度之间的关系,作了分析说明。等厚条纹受到同时出现的等色条纹的调制,前者给出主应力和σ1+σ2的分布,后者同主应力差σ1-σ2的分布有关。所以,由这个方法得到的单张条纹图,为分别确定两个主应力提供了充分的资料。几个二维问题被引作例子,并描述了完成实验所需要的一些实用方法。本文也讨论了这个方法用于一般三维冻结应力模型的可能性。

目的:检查左旋氧氟沙星在体外的抗分支杆菌活性。设计:用7h11培养基,以琼脂稀释方法测左旋氧氟沙星对不同种的分支杆菌的最小抑制浓度(MIC),并与氧氟沙星比较。左旋氧氟沙星对于被小鼠腹腔巨噬细胞吞食的结核分支杆菌和胞内分支杆菌的抗微生物活性是以菌落形成单位(CFU)的减少来衡量的。结果:左旋氧氟沙星抗结核分支杆菌、堪萨斯分支杆菌、海鱼分支杆菌、瘰疬分支杆菌、鸟分支杆菌、胞内分支杆菌、偶然分支杆菌和龟分支杆菌的MIC比氧氟沙星的MIC低2到4倍。左旋氧氟沙星减少巨噬细胞内CFU的效果高于氧氟沙星。结论:左旋氧氟沙星比氧氟沙星具有更强的体外抗分支杆菌活性。
