University of Science and Technology, Kunming 650093, China Received 25 May 2014; accepted 8 December 2014 Abstract: In order to recycle waste Sn-based alloys, the vapor-liquid phase equilibrium composition... words: Sn-based alloys; activity coefficient; vacuum distillation; vapor-liquid phase equilibrium 1 Introduction Sn is one of the earliest metals that human discovered and used and is widely used......
and the shrinking ratio is 2.8% compared with the pure vanadium. The main precipitation in the bulk grains is the complex Ti rich Ti-CNO phase, which has a plate shape with the width of about 100 nm... of precipitation, which has a square shape and the size is about 500 nm. The size of plate shape precipitation is reduced. Key words: vanadium alloy; microstructure; second phase ......

alloy were predicted. The vapor-liquid phase equilibrium of Pb-Sn-Sb alloy system was calculated using the activity coefficients of Pb-Sn-Sb alloy system in the process of vacuum distillation. The calculated results show that the content of Sn in vapor phase increases with the increasing distillation temperature and content of Sn in liquid phase. However, the content of Sn in vapor phase is only 0.45......
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......
