Phase Behavior of Rare Earth Manganites Jian Meng1,Hiromi Nakano2,Naoki Kamegashira3,Gang CHEN4 (1.Key Laboratory of Rare Earth Chemistry an Physics,Changchun Institute of Applied Chemistry,Chinese... BaLn2Mn2O7 (Ln=rare earth) with the layered perovskite type and Ln2(Mn, M)O7 with pyrochlore-related structure were studied since these compounds show many kinds of phases and unique phase transitions......
Effect of hydrolysis conditions on hydrous TiO2 polymorphs precipitated from a titanyl sulfate and sulfuric acid solutionHao Song, Bin Liang, Li Lü, Pan Wu, and Chun Li Department of Metallurgical... the titania crystal phase. Hydrous TiO 2 in the form of rutile, anatase, or the mixture of both could be obtained in solutions of low titanium concentrations and 2.5wt% to 15wt% sulfuric acid at 100 C......
时效温度对铸造超级双相不锈钢析出相的影响向红亮1,何福善1,刘东1(1.福建省福州市福州大学机械工程及自动化学院)摘 要:对固溶处理后的铸造超级双相不锈钢材料进行时效处理,利用OM,SEM,XRD和TEM分析了时效温度对析出相的影响.结果表明,固溶后经时效处理,金属间相在铁素体内和铁素体/奥氏体晶界析出;650℃时效时,析出的金属间相主要是χ相;750℃时效时析出σ相和χ相,此时σ相由χ相演变而来;850℃时效下则直接析出σ相;950℃时效后,少量的σ相仅在铁素体/奥氏体晶界产生.关键词:铸造超级......

(2020) 27: 2220-2226 DOI: https://doi.org/10.1007/s11771-020-4443-6 Phase investigations of manganese–bismuth alloyed in a microwave furnace Panita THONGJUMPA1, Thanida... because the ferromagnetic low-temperature phase (LTP) is not exclusively obtained. In this work, melting powered by four commercial magnetrons of 2000–2500 W in a microwave furnace is demonstrated......
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......
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......
or χ-Al2O3·TiO2 phase. After heat treatment, γ-Al2O3 in the coatings transforms to α-Al2O3, and rutile is precipitated. Key words: Al2O3-13%TiO2; nanocrystalline powder; nanocoatings; phase evolution 1... to α-Al2O3 and TiO2 phase precipitated during heat treatment. Because of stresses associated with the volume change, the phase transformation will deteriorate thermal shock resistance of the coatings......
