| 1 | Microstructure studies of air-plasma-spray-deposited CoNiCrAlY coatings before and after thermal cyclic loading for high-temperature application显示文摘In the present study, bond-coats for thermal barrier coatings were deposited via air plasma spraying(APS) techniques onto Inconel 800 and Hastelloy C-276 alloy substrates. Scanning electron microscopy(SEM), transmission electron microscopy(TEM), X-ray diffraction(XRD), and atomic force microscopy(AFM) were used to investigate the phases and microstructure of the as-sprayed, APS-deposited Co Ni Cr Al Y bond-coatings. The aim of this work was to study the suitability of the bond-coat materials for high temperature applications. Confirmation of nanoscale grains of the γ/γ′-phase was obtained by TEM, high-resolution TEM, and AFM. We concluded that these changes result from the plastic deformation of the bond-coat during the deposition, resulting in Co Ni Cr Al Y bond-coatings with excellent thermal cyclic resistance suitable for use in high-temperature applications. Cyclic oxidative stability was observed to also depend on the underlying metallic alloy substrate. | Dipak Kumar K.N.Pandey Dipak Kumar Das | 2016 | International Journal of Minerals,Metallurgy and Materials2016，23，8： | 6 |
| 2 | Isothermal Grain Growth of Austenite in Hypoeutectoid and Hypereutectoid Plain Carbon Steels显示文摘Grain growth kinetics of austenite in a hypoeutectoid steel(containing carbon of 0.35%)at 920 ℃ and in a hypereutectoid steel(containing carbon of 1%)at 980 ℃ for holding time ranging from 1 h to 6 h was investigated.The hypoeutectoid steel exhibited normal grain growth without solute drag hindrance with a time exponent(0.51)close to the theoretical value(0.5).However,the grain growth of austenite in the hypereutectoid steel held up to 3 h was extremely slow,characterizing by a low value of time exponent(0.08).Thereafter,a breakaway occurred and the grain growth in the hypereutectoid steel held from 3 h to 6 h progressed normally with a time exponent(0.52)close to the theoretical value(0.5). | Joydeep Maity Dipak Kumar Mondal | 2010 | Journal of Iron and Steel Research(International)2010，17，7： | 5 |
| 3 | Fire monitoring in coal mines using wireless underground sensor network and interval type-2 fuzzy logic controller显示文摘From the view of underground coal mining safety system, it is extremely important to continuous monitoring of coal mines for the prompt detection of fires or related problems inspite of its uncertainty and imprecise characteristics. Therefore, evaluation and inferring the data perfectly to prevent fire related accidental risk in underground coal mining (UMC) system are very necessary. In the present article, we have proposed a novel type-2 fuzzy logic system (T2FLS) for the prediction of fire intensity and its risk assessment for risk reduction in an underground coal mine. Recently, for the observation of underground coal mines, wireless underground sensor network (WUSN) are being concerned frequently. To implement this technique IT2FLS, main functional components are sensor nodes which are installed in coal mines to accumulate different imprecise environmental data like, temperature, relative humidity, different gas concentrations etc. and these are sent to a base station which is connected to the ground observation system through network. In the present context, a WUSN based fire monitoring system is developed using fuzzy logic approach to enhance the consistency in decision making system to improve the risk chances of fire during coal mining. We have taken Mamdani IT2FLS as fuzzy model on coal mine monitoring data to consider real-time decision making (DM). It is predicted from the simulated results that the recommended system is highly acceptable and amenable in the case of fire hazard safety with compared to the wired and off-line monitoring system for UMC. Legitimacy of the suggested model is prepared using statistical analysis and multiple linear regression analysis. | Sweta Basu Sutapa Pramanik Sanghamitra Dey Gautam Panigrahi Dipak Kumar Jana | 2019 | International Journal of Coal Science & Technology2019，6，2： | 2 |
