Fault diagnosis and process monitoring using a statistical pattern framework based on a self-organizing mapSONG Yu(宋羽), JIANG Qing-chao(姜庆超), YAN Xue-feng(颜学峰) (Key Laboratory of Advanced Control and Optimization for Chemical Processes of Ministry of Education(East China University of Science and Technology), Shanghai 200237, China)Abstract:A multivariate method for fault diagnosis and process......
was observed by scanning electron microscope to investigate the formation of hard and brittle probable phases. The effect of anneal time on diffusion distance and phase transformation was also analysed... to the interface after anneal treating for 3 h and δ phase was thicker and more continuous by increasing annealing time. The microhardness measurement showed that in spite of formation of δ phase due to diffusion......
Isothermal precipitation and growth process of perovskite phase in oxidized titanium bearing slag WANG Ming-yu(王明玉)1, WANG Xue-wen(王学文)1, HE Yue-hui(贺跃辉)2, LOU Tai-ping(娄太平)3, SUI Zhi-tong(隋智通)3... titanium bearing slag was studied by quenching method. The kinetics of precipitating process and crystal growth of perovskite phase was analyzed. The results show that the precipitating and growth......
