). As a result, a series of spinel Li1+x+yMn2-xO4 compounds are given in the Li-Mn-O phase diagram with the average valent of Mn varied from 3 to 4[1, 9, 10]. For examples, at x = 0 and y = 1, the stoichiometric...) For the case of 2x+y=1 In this case, Li2MnO3 phase does not form. The oxidization of Li2Mn2O4 is only resulted from the transfer of Li+ from tetrahedral 8a sites to octahedral 16d sites......
MULTI-PEAK MATCH INTENSITY RATIO METHOD OF QUANTITATIVE X-RAY DIFFRACTION PHASE ANALYSIS G.Chu1,H.J.You1,Y.F.Cong1 (1.Research Center of Analysis and Test, Liaoning University of Petroleum & Chemical Technology, Fushun 113001, China) Abstract:A new method for quantitative phase analysis is proposed by using X-ray diffraction multi-peak match intensity ratio. This method can obtain the multi......
Liquid phase separation of Cu-Cr alloys during rapid cooling SUN Zhan-bo(孙占波), WANG You-hong(王宥宏), GUO Juan(郭 娟) School of Science, Xi’an Jiaotong University, Xi’an 710049, China Received 10... were analyzed by scanning electron microscopy and transmission electron microscopy. The results reveal that a representative liquid phase separation microstructures are observed in Cu75Cr25 ribbons......

Effect of Temperature and Phase Constitution on Kineties of La Diffusion 夏立芳1,刘志儒1,阎牧夫1 (1.School of Materials Science and Engineering, Harbin Institut e of Technology, Harbin 150001, China) Abstract:The diffusion of La in ε-Fe2~3N(ε)and γ′-Fe4N (γ′)phases pro duced by plasma nitriding was studied. It is found that with increasing nitridin g time, the ε phase continuously decomposes into γ......
