the Y-NiMo phase existed. The recrystallization process in the interdendritic region was significantly inhibited by the Y-NiMo precipitates. However, the pinning effect gradually weakened with the annealing time due to the dissolution of the Y-NiMo phase, and the recrystallization depth in the dendrite arm was deeper than that in the interdendritic region. Key words: recrystallization; kinetics; Y......

PHASE TRANSFORMATION BEHAVIOR IN THE SPUTTERDEPOSITED Ti-Pd-Ni THIN FILMS J.S.Wu1,Q.C.Tian1 (1.Key Laboratory of the Ministry of Education for High Temperature Materials and Tests,School... calorimetry (DSC). It was found that the phase transformation temperatures of Ti50.6Pd30Ni19.4 ingot are much higher than those of its thin film. The B19'' and B19 phases coexisted, together with the Ti2Ni......
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......
Phase Transformations in Low-Fe Alloys of the Al-Cu-Fe System Liming Zhang1 (1.Department for Earth and Environmental Science, Crystallography section, Ludwig-Maximillian- Universitat Munchen, Theresienstrasse 41, D-80333 Munchen, Germany) 摘要:Microstructure and phase transformation in the Al-Cu-Fe alloys of the approximate compositional range of 20 -50 at.% Cu and 2 - 10 Fe at.% have been......
