Novel Phase Transition in BaPr2Mn2O7 Hiromi Nakano1,Naoki Kamegashira2 (1.Ryukoku University, Seta, Otsu 520-2194, Japan;2.Toyohashi University of Technology, Tenpaku-cho, Toyohashi 441-8580, Japan... homologous series AO(ABO3)2. In Pr-manganite, a novel phase transition was first observed in situ at 1040 K by a thermal transmission electron microscope. At 1040 K, reflections began to split along the c......
Effect of Stable Magnetic Field on the Phase Transformation of Sr3 Steel WANG Yan-an1,LIAO Dai-qiang1,WU Zhan-jun1 (1.Anshan University of Science and Technology, Anshan 114044, China) 摘要... on the phase transformation of Sr3 steel was studied by metallographic microscope and scanning electron microscope. The result shows: the application of magnetic field can obviously increase the volume......
