| 1 | EFFECT OF REVERT RECYCLE TIMES ON MICROSTRUCTURE AND FATIGUE PROPERTIES IN COBALT-BASE SUPERALLOY K640S显示文摘Effect of revert cycles on microstructure and fatigue properties of cast cobalt base superalloy K640S has been investigated. The results show that: at 70 times of cool heat cycles, there were microcracks found in seven times revert and ten times revert. With the increasing of thermal fatigue cycles, the crack of revert grows a little faster than virgin. When the cycle time reaches 200, the crack length for both virgin and reverts have been as long as 2mm. The low cycle fatigue life has no remarkable change, with the increase of revert cycles at 815℃, 360MPa ,0 5Hz. With the times of cycles increasing, it is found that the content of impurity and gas in alloy change a little, and there is no obvious change for dendrite microstructure. | T.L. Wang 1,2) , J.T.

| 8 | STUDY OF MICROSTRUCTURE ON PAN-ACFs PREPARED BY DIFFERENT ACTIVATION METHODS显示文摘Polyacrylonitrile (PAN) -based activated carbon fibers (ACFs) are amorphous graphitic carbon, consisting of sp2 hexagonal carbon layers with different sizes of pores ranging from micropores to macropores. The microstructure, including graphite-like micro-crystal, surface chemistry, pore size distributions and so on, of PAN activated carbon fibers prepared by different activation methods were investigated by element analysis (EA), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and infrared spectra. The XRD patterns show that PAN-ACFs activated by different methods are of amorphous diffraction characteristic but composed of very small graphitic crystallites. The surface functional groups were analyzed by XPS and FT-JR spectra. The samples activated by air possess relatively abundant oxygen functional groups, and the samples activated by potassium hydroxide possess less oxygen functional groups. This is attributed to the different activation mechanisms. | Z.Y. Ryu, H.Q. Rong, J.T. Zheng, M.Z. Wang and B.J Zhang (Institute of coal chemistry, The Chinese Academy of Sciences, P. O.
