Phase selection in highly undercooled Fe-B eutectic alloy melts YANG Chang-lin(杨长林), YANG Gen-cang(杨根仓), LU Yi-ping(卢一平), CHEN Yu-zeng(陈豫增), ZHOU Yao-he(周尧和) State Key Laboratory... technique by molten glass slag purification and cyclical superheating in Ar atmosphere was applied to bulk Fe-B alloy melts. A hypercooling was achieved which suppressed the formation of stable phase......
CONTACT MATERIALS FOR GaSb AND InSb: A PHASE DIAGRAM APPROACH K.W.Richter1,H.Ipser1 (1.Institut für anorganische Chemie,Universitat Wien Wathringerstrasse 42,A-1090 Vienna,Austria) Abstract... includes the exposure to elevated tempera-tures, interface reactions often occur during metallization and further heat treatment.It is thus important to understand the respective phase equilibria......
by thermomechanical processes such as hot extrusion [16-18]. Quasicrystal I-phase has high hardness, good thermal stability, high corrosion resistance and low interfacial energy [19]. Besides, I-phase particles are stable against coarsening and can effectively impede the slip of dislocations during hot deformation [20-22]. In addition to the icosahedral quasicrystal I-phase, some second phases are also present......
Phase field modeling of dendrite growth Chengzhi WANG1,Yiyi LI2,Yutuo ZHANG1,Dianzhong LI2 (1.Shenyang Ligong University,Shenyang 110168,China;2.Institute of Metal Research,Chinese Academy of Sciences,Shenyang 110016,China) Abstract:Single dendrite and multi-dendrite growth for A1-2 mol pct Si alloy during isothermal solidification are simulated by phase field method. In the case of single......

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......
J. Cent. South Univ. (2017) 24: 48-55 DOI: 10.1007/s11771-017-3407-y Liquidus and phase equilibria in CaO-SiO2-5%MgO-20%Al2O3-TiO2 system SUN Li-feng(孙丽枫)1, 2, SHI Jun-jie(石俊杰)1, 2, ZHANG Bo(张波)1, 2... technique (SHTT) and high temperature equilibrium technique were combined to investigate the phase diagram of the CaO-SiO2-5%MgO-20%Al2O3-TiO2 system. The 1300 °C to 1500 °C liquidus lines......
