; 文献标志码:A Controllable phase transformation of anodic TiO2 nanotube arrays and its characterization MA Qing1, 2, CHEN Jian-jun1, FU Dong-ju1, LI... anatase to rutile phase transformation (ARPT) was realized by annealing anodic TiO2 nanotube arrays (TNTs) in O2, N2, 5%H2+95%N2 (volume fraction) and NH3 atmospheres at temperature range of 400-650......
DSC Investigation of Phase Transitions in System LaH2-LaH3 王龙妹1 (1.Central Iron & Steel Research Institute, Beijing 100081, China) Abstract:Differential scanning calorimetry (DSC) measurements... complicated DSC signals (double, triple etc. peaks) were observed which some of them were up to 4 phase transformations. Based on these measurements and carried out on high purity samples and supported......

; accepted 31 July 2020 Abstract: The effect of the amount of Sn on the formation of fcc phase in Ti-13Ta-xSn (x=3, 6, 9 and 12, at.%) alloys was studied. The alloys were synthesized by mechanical alloying using a planetary mill, jar and balls of stabilized yttrium. Using Rietveld refinement, it was found that the obtained fcc phase has crystallite size smaller than 10 nm and microstrain larger than......
